# VirtualDJ VDJScript API Reference

Curated API-oriented reference for VDJScript used in skins, pad pages, custom buttons, and controller mappings.

This file now has two layers:

- The curated API layer at the top: canonical names, aliases, scripting surfaces, and reliability notes.
- The broad catalog below: wide coverage tables that are still being normalized.

## Status

This is the first API pass, not the final exhaustive pass.

The highest-confidence material in this file is the curated layer at the top. It is intentionally biased toward the verbs and patterns that matter most for:

- skin XML
- pad page XML
- custom button actions
- controller mappings
- small inline query and text scripts

Current curated coverage includes:

- flow and timing verbs
- variables and deck targeting
- skin panels and settings
- browser, search, and sideview actions
- transport, cue, loop, and sync controls
- filter and FX selection
- FX stems routing, release controls, and controller-oriented armed FX helpers
- sampler page-aware helpers
- deck assignment and crossfader routing

## Reliability Labels

- `Official`: current VirtualDJ manual or VDJPedia
- `Official forum`: VirtualDJ staff, Development Manager, CTO, or Support staff forum guidance. Adion/CTO replies should be treated as high-authority implementation notes for scripting, audio-engine, and feature-behavior questions; VirtualDJ forum badges identify Adion as CTO, and Atomix's press archive confirms the 2011 AdionSoft acquisition.
- `Community`: forum guidance from non-staff users
- `Published skin`: observed in a working public skin; use as provenance and a prompt for testing, not as sole semantic authority
- `Built-in skin`: observed in skin XML shipped inside the VirtualDJ app bundle; treat as semi-official executable evidence, then curate before recommending
- `Published pad page`: observed in a working public pad page; use as provenance and a prompt for testing, not as sole semantic authority
- `Built-in pad page`: observed in pad-page XML shipped inside the VirtualDJ app bundle; treat as semi-official executable evidence, then curate before recommending
- `Built-in app resource`: command name, description, or UI catalog entry observed in non-skin/non-pad resources shipped inside the VirtualDJ app bundle
- `Binary string-table`: command-looking string observed in the VirtualDJ executable; use for discovery only, not as behavior evidence
- `Local test`: behavior reproduced in VirtualDJ locally
- `Inference`: a conclusion drawn from official behavior plus repo usage

## Surface Legend

- `Map`: controller mapping
- `Button`: custom button action
- `Pad`: pad page action or query
- `SkinAction`: skin `action=""`, inline button body, or interactive element action
- `SkinQuery`: skin `query=""`, `visibility=""`, `condition=""`, or equivalent boolean/value query slot
- `Text`: skin `text`, `format`, color backticks, or other string/value-returning query usage

These are practical surfaces, not hard type-check guarantees. When a surface is listed, read it as "commonly useful and normally safe there", not "the only place the verb can run".

## Alias Policy

- Use the primary name shown in the current official verbs page as the canonical heading.
- List official aliases explicitly.
- Prefer canonical names in examples unless the alias is the name people are most likely to search for.
- If a synonym is only found in community posts and not in the official manual, label it as community-only rather than treating it as an official alias.

## Published-Skin Evidence Policy

- Preserve commands observed in working public skins even when older local docs do not mention them.
- Always record the skin path, skin metadata, and exact line references before promoting a finding into the curated layer.
- Search the current official manual and VirtualDJ forums for each term; the local Markdown files can lag behind the live docs.
- Mark untested behavior as `Needs local test` instead of deleting or normalizing it away.
- Keep empirical source notes in [Published Skin Findings](Published%20Skin%20Findings.md) so future edits can see why an unfamiliar verb is present.

## Official Appendix Coverage

The local reference now has names-only coverage for all 991 official names tracked in [Official VDJScript Coverage Audit](Official%20VDJScript%20Coverage%20Audit.md). Use that audit before removing or dismissing any unfamiliar command.

Coverage depth is tiered:

- Curated entries near the top are the highest-confidence API notes.
- Broad catalog sections below cover common usage in a compact form.
- Current official-name coverage is 991/991 with 0 missing names.
- The [Official Appendix Remainder](#official-appendix-remainder) section is kept as an audit marker; all tracked official names are currently searchable in functional sections, so the compact official remainder is empty.
- The remaining formal `Needs local test` gap is 19 sparse or hardware-specific official names; build/context results belong in [VDJScript Local Test Tracker](VDJScript%20Local%20Test%20Tracker.md).

Promote compact official entries into curated sections when they become relevant to skins, pads, mappings, published-skin findings, or local tests.

## Core Execution Model

### Action vs Query vs Dual Verbs

- `Action` verbs primarily do something: `play_pause`, `load`, `skin_panel`
- `Query` verbs primarily return information: `get_browsed_song`, `get_time`, `sampler_loaded`
- `Dual` verbs are often used both ways: `filter`, `setting`, `var`

When a verb is documented here as `Dual`, that means it is commonly used in both action chains and value/query contexts.

### Deck Scoping

VDJScript actions can be prefixed with deck context:

```vdjscript
deck 1 play
deck 2 volume 50%
deck master get_level
```

Use deck scoping whenever the result should be explicit instead of depending on the current focused deck.

Notes:

- `deck master` means "run this in the current master deck context".
- In sampler title and text paths, explicit `deck 1 ... : deck 2 ...` resolution can be more reliable than raw `deck master ...`.

- `Official forum`: sampler sync/build-specific discussion around master-deck sampler routing

## Curated High-Frequency Entries

### `nothing`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Do nothing

Typical forms:

```vdjscript
nothing
has_cue 1 ? nothing : goto_first_beat & set_cue 1
```

Important behavior:

- `nothing` is a no-op action, not a control-flow exit.
- It does not stop the rest of an action chain from running.
- Use it as the empty branch of a conditional; put the whole guarded routine inside the opposite branch when you want to skip that routine.

```vdjscript
has_cue 1 ? nothing : goto_first_beat & set_cue 1 & goto +32bt & set_cue 2
```

Sources:

- `Official`: VDJScript verbs appendix, `nothing` action
- `Inference`: no-op/branching implication from VDJScript action-chain behavior

### `up`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Branch on press versus release

Typical forms:

```vdjscript
up ? action_on_press : action_on_release
```

Use when:

- you need separate press/release logic in controller mappings
- you want momentary behavior without relying on vars

Sources:

- `Official`: VDJScript verbs appendix

### `down`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Branch on press versus release

Typical forms:

```vdjscript
down ? action_on_press : action_on_release
```

Preferred usage:

- use for hold-style momentary effects and pad behaviors
- pair with `filter 50%` or another neutral reset on the release side when the control is momentary

Sources:

- `Official`: VDJScript verbs appendix

### `holding`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Branch based on whether the control was held long enough

Typical forms:

```vdjscript
holding ? long_press_action : short_press_action
holding 1000ms ? long_press_action : short_press_action
```

Notes:

- The default threshold is documented as `500ms`.
- Prefer this over hand-rolled timer vars when you only need short-press versus long-press behavior.

Sources:

- `Official`: VDJScript verbs appendix

### `doubleclick`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Branch based on whether the control was pressed twice within the allowed window

Typical forms:

```vdjscript
doubleclick ? double_action : single_action
doubleclick 1000ms ? double_action : single_action
```

Notes:

- The default interval is documented as `300ms`.

Sources:

- `Official`: VDJScript verbs appendix

### `repeat_start`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Start a named repeating task after the first interval passes

Typical forms:

```vdjscript
repeat_start 'scroll' 1000ms & browser_scroll +1
repeat_start 'pulse' 1bt
repeat_start 'name' `get_var interval_ms`
```

Preferred usage:

- use named repeats for background animation, repeated browser movement, and timed FX patterns
- always pair long-lived repeats with a clear `repeat_stop`

Sources:

- `Official`: VDJScript verbs appendix

### `repeat_start_instant`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Start a named repeating task immediately, then keep repeating on the chosen interval

Typical forms:

```vdjscript
repeat_start_instant 'scroll' 250ms & browser_scroll +1
```

Preferred usage:

- use when the first action should happen right away rather than after the first delay

Sources:

- `Official`: VDJScript verbs appendix

### `repeat_stop`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Stop a repeat created with `repeat_start` or `repeat_start_instant`

Typical forms:

```vdjscript
repeat_stop 'scroll'
```

Sources:

- `Official`: VDJScript verbs appendix

### `wait`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Delay the next action in a chain

Typical forms:

```vdjscript
wait 1bt & pause
wait 500ms & play
```

Notes:

- Use it for simple timed chains.
- If you need a persistent process, prefer named repeats instead of stacking many waits.

Sources:

- `Official`: VDJScript verbs appendix

### `blink`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Pad`, `SkinQuery`

Official summary:

- Toggle LED or visual state on and off at a configurable rate

Typical forms:

```vdjscript
blink
blink 1000ms
blink 1bt
blink 1bt 25%
```

Preferred usage:

- use as the true branch in queries: `effect_active 1 ? blink 1bt : off`

Sources:

- `Official`: VDJScript verbs appendix

### `param_bigger`

Aliases: `param_greater`

Kind: `Dual`

Typical surfaces: `Map`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Compare the caller value against a value or another action result

Typical forms:

```vdjscript
param_bigger 0 ? action1 : action2
param_bigger pitch pitch_slider
```

Preferred usage:

- use the canonical manual name `param_bigger` in docs
- mention `param_greater` when helping users search or migrate older scripts

Sources:

- `Official`: VDJScript verbs appendix

### `param_equal`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Compare the caller value or the first parameter value against another value

Typical forms:

```vdjscript
param_equal `get_browsed_song 'type'` "audio"
param_equal 0.5 filter ? on : off
```

Preferred usage:

- use backticks when the compared value comes from another action
- prefer this over brittle string slicing or var mirrors when the source action already returns the value you need

Sources:

- `Official`: VDJScript verbs appendix

### `var`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Test whether a variable is true

Typical forms:

```vdjscript
var "my_var" ? action1 : action2
var '$global_shift' ? action1 : action2
var '@$skin_mode' ? action1 : action2
```

Notes:

- Use vars when you truly need stored state across events.
- Do not reach for vars when a built-in query verb already answers the question directly.
- Variable names control scope. Plain names such as `my_var` are deck-local; `$my_var` is global; `@` variants are saved across sessions. See "Variable Scope" below before using vars for skin-wide layout or controller-wide modes.

Sources:

- `Official`: VDJScript verbs appendix
- `Community`: experienced skin scripters repeatedly caution against overusing vars when a built-in UI/query path already exists

### `set`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Set a variable to a value

Typical forms:

```vdjscript
set 'varname' 5
set 'page_fx_active' 1
set 'remembered_filter' `filter`
set '$global_mode' 1
set '@$layout_4deck' 1
```

Notes:

- Use for stored state, not as a substitute for native UI or deck state queries.
- Match the variable prefix to the intended scope. A plain `set 'mode' 1` stores a deck-local value, which can differ on another deck.

Sources:

- `Official`: VDJScript verbs appendix, variable section

### `toggle`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Toggle a variable between true and false

Typical forms:

```vdjscript
toggle 'MyVar'
toggle '$MyVar'
toggle '@$show_zoom_racks'
toggle '$rmbrowser'
toggle '$rmsettings'
```

Preferred usage:

- good for explicit user modes
- avoid using it when the target should mirror a built-in state such as `play`, `loop`, or `masterdeck`
- the variable prefix is part of the variable identity. `toggle 'MyVar'` and `toggle '$MyVar'` change two different variables.
- query a global variable with the same global name, for example `var_equal '$MyVar' 1 ? action1 : action2`
- bundled Remote skins use `toggle '$rmbrowser'` for full-screen deck/browser view switching and `toggle '$rmsettings'` for the settings overlay; the matching panels use `visibility="var '$rmbrowser' 0/1"` and `visibility="var '$rmsettings' 1"`

Sources:

- `Built-in skin`: `examples/Skins/Built-In/Remote/9x16P.xml`, `9x16T.xml`, `3x4T.xml`, `16x9T.xml`

### `get_var`

Aliases: none

Kind: `Query`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Return the value of a named variable

Typical forms:

```vdjscript
get_var 'varname'
get_var '$global_mode'
```

Sources:

- `Official`: VDJScript verbs appendix

### Variable Scope

VDJScript variable scope is encoded in the variable name prefix.

| Form | Scope | Saved Across Sessions | Example |
| --- | --- | --- | --- |
| `name` | local to the current deck | no | `set 'pad_mode' 1` |
| `#name` | local to the current deck | no | `set '#pad_mode' 1` |
| `%name` | local to a logical deck reference | no | `deck left set '%pad_mode' 1` |
| `$name` | global to both/all decks | no | `set '$shift' 1 while_pressed` |
| `@name` | persistent local deck variable | yes | `set '@skin_view' 1` |
| `@%name` | persistent local logical-deck variable | yes | `set '@%skin_view' 1` |
| `@$name` | persistent global variable | yes | `set '@$layout_4deck' 1` |

Notes:

- Plain variables are deck-local. `deck 1 set 'mode' 1` and `deck 2 var 'mode'` are different variable slots.
- `$` variables are global and are the right choice for a mode that should be shared by both decks during the current VirtualDJ session. The `$` is part of the variable name: `MyVar` and `$MyVar` are different variables, so a global variable must be queried as global too.
- `@` variables are saved across sessions. Use `@$...` for skin-wide persistent layout state.
- `%` variables are also deck-local, but tied to the logical deck reference. The official wiki notes that `deck 1 '%myvar'` and `deck left '%myvar'` can have different values even when deck 1 is currently the left deck.
- In init/controller setup paths, prefer explicit numbered deck targets when setting local variables, for example `deck 1 set 'var1' 0.5`. Community forum testing found `deck left set '%varx' 0.5` unreliable in an init context, and a moderator noted that `left` is a current role rather than a real numbered deck.
- Variables persist while VirtualDJ is running; they are not scoped to a particular controller or skin. Use distinctive names for skin/controller variables to avoid collisions.

### `set_deck`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Use a script result or implicit value to decide which deck the following action applies to

Typical forms:

```vdjscript
set_deck `get_var target_deck` & play
```

Preferred usage:

- use in mappings when the target deck is computed at runtime
- prefer explicit `deck 1 ...`, `deck 2 ...`, or `deck master ...` when the target is already known

Sources:

- `Official`: VDJScript verbs appendix

### `skin_panel`

Aliases: `skin_pannel`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Show or hide a named panel

Typical forms:

```vdjscript
skin_panel 'my_panel' on
skin_panel 'my_panel' off
skin_panel 'rmbrowser' on
```

Preferred usage:

- use for explicit panel toggles
- if panel visibility should simply follow a live condition, prefer panel `visibility=""` or other query-driven skin logic instead of setting extra vars only to call `skin_panel`
- bundled wide Remote phone skins use `skin_panel 'rmbrowser' on` to select a browser panel inside `group="rmporpanels"`; nearby elements hide with queries such as `visibility="skin_panel 'rmbrowser' ? no : yes"`
- for Remote touch tabs, prefer `skin_panel '<panel-name>' on` over `skin_panelgroup` when selecting a named panel in a group

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: Skin SDK panel documentation
- `Built-in skin`: Remote tab buttons use `skin_panel ... on`
- `Local test`: Grave Raver Remote top navigation did not react reliably with `skin_panelgroup`
- `Built-in skin`: `examples/Skins/Built-In/Remote/16x9P.xml`, `19x9P.xml`

### `skin_panelgroup`

Aliases: `skin_pannelgroup`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Switch which panel in a named group is shown

Typical forms:

```vdjscript
skin_panelgroup 'rack' 'fx'
skin_panelgroup 'rack' +1
skin_panelgroup 'rack' 0.75
```

Preferred usage:

- use when the user is deliberately switching between remembered panel modes
- for Remote top-level touch tabs, prefer direct `skin_panel '<panel-name>' on`; use `skin_panelgroup` for generic panel-group cycling or contexts where it has been verified
- use `skin_panelgroup_available` to keep unavailable panels out of cycles

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: Skin SDK panel documentation
- `Local test`: Grave Raver Remote top navigation did not react reliably with `skin_panelgroup`

### `lock_panel`

Aliases: `lock_pannel`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `SkinAction`

Official summary:

- Despite the name, this acts on `<split>` elements rather than `<panel>`

Notes:

- Document this quirk explicitly wherever the verb is mentioned.

Sources:

- `Official`: VDJScript verbs appendix

### `setting`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Read or write a specific VirtualDJ setting

Typical forms:

```vdjscript
setting "jogSensitivityScratch" 80%
setting "videoRandomTransition" on
setting "filterDefaultResonance"
```

Preferred usage:

- prefer it for actual program settings such as `filterDefaultResonance`
- do not use settings as a substitute for temporary UI state that belongs in a script variable or a panel selection

Sources:

- `Official`: VDJScript verbs appendix
- `Official forum`: `setting filterDefaultResonance` recommended by CTO Adion for filter resonance scripting

### `settings`

Aliases: `config`

Kind: `Action`

Typical surfaces: `Map`, `Button`

Official summary:

- Open the configuration window

Sources:

- `Official`: VDJScript verbs appendix

### `display_time`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Set the displayed time mode to `total`, `remain`, `elapsed`, `+1`, or `-1`

Typical forms:

```vdjscript
display_time 'remain'
display_time 'remain,elapsed'
display_time +1
```

Preferred usage:

- prefer this over custom elapsed/remain vars when the goal is simply to switch the time-display mode

Sources:

- `Official`: VDJScript verbs appendix
- `Inference`: prefer the built-in time-display mode before inventing a parallel time-mode variable

### `get_time`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`, `Map`, `Button`

Official summary:

- Return elapsed, remaining, or total time, with optional unit and target-point arguments

Typical forms:

```vdjscript
get_time
get_time 'remain'
get_time 'remain' 'short'
get_time 1000
get_time 'absolute'
```

Notes:

- `get_time` follows the current `display_time` mode unless you explicitly pass `elapsed`, `remain`, or `total`.
- The official verbs appendix also lists target-point forms such as `get_time 'to_lyrics'`. Treat `to_lyrics` as useful but lightly documented; verify exact return behavior in the target skin/build before designing around it.

Sources:

- `Official`: VDJScript verbs appendix

### Time Component Queries

Use these when a skin needs separate time fields instead of the formatted string from `get_time`.

| Verb | Surfaces | Summary | Example |
| --- | --- | --- | --- |
| `get_time_sign` | `Text`, `SkinQuery` | Return `-1` or `+1` for elapsed/remain/total time according to `display_time`. | `get_time_sign 'remain'` |
| `get_time_hour` | `Text`, `SkinQuery` | Hour component of elapsed/remain/total time. | `get_time_hour 'elapsed'` |
| `get_time_min` | `Text`, `SkinQuery` | Minute component of elapsed/remain/total time. | `get_time_min 'remain'` |
| `get_time_sec` | `Text`, `SkinQuery` | Second component of elapsed/remain/total time. | `get_time_sec 'remain'` |
| `get_time_ms` | `Text`, `SkinQuery` | Hundredth-second component of elapsed/remain/total time. | `get_time_ms 'elapsed'` |
| `get_time_msf` | `Text`, `SkinQuery` | Frame component of elapsed/remain/total time. | `get_time_msf 'elapsed'` |
| `get_totaltime_min` | `Text`, `SkinQuery` | Minute component of total track length. | `get_totaltime_min` |
| `get_totaltime_sec` | `Text`, `SkinQuery` | Second component of total track length. | `get_totaltime_sec` |
| `get_totaltime_ms` | `Text`, `SkinQuery` | Hundredth-second component of total track length. | `get_totaltime_ms` |
| `get_totaltime_msf` | `Text`, `SkinQuery` | Frame component of total track length. | `get_totaltime_msf` |
| `get_songlength` | `Text`, `SkinQuery` | Total track length in seconds. | `get_songlength` |

Notes:

- Most `get_time_*` verbs follow `display_time`; pass `elapsed`, `remain`, or `total` to bypass the current display mode.
- Use the broader `get_time` entry for formatted text and arbitrary unit conversion.

Sources:

- `Official`: VDJScript verbs appendix

### Loaded Track Metadata Queries

These query the track loaded on the current deck, unlike `get_browsed_*`, which follows the browser selection.

| Verb | Surfaces | Summary | Example |
| --- | --- | --- | --- |
| `get_filepath` | `Text`, `SkinQuery` | Full file path of the loaded song. | `get_filepath` |
| `get_filename` | `Text`, `SkinQuery` | File name of the loaded song. | `get_filename` |
| `get_filesize` | `Text`, `SkinQuery` | File size of the loaded song. | `get_filesize` |
| `get_composer` | `Text`, `SkinQuery` | Composer tag of the loaded song. | `get_composer` |
| `get_year` | `Text`, `SkinQuery` | Year tag of the loaded song. | `get_year` |
| `get_artist_title` | `Text`, `SkinQuery` | Combined artist-title text for the loaded song. | `get_artist_title` |
| `get_title_artist` | `Text`, `SkinQuery` | Combined title-artist text for the loaded song. | `get_title_artist` |
| `get_title_remix` | `Text`, `SkinQuery` | Title plus remix in parentheses. | `get_title_remix` |
| `get_artist_before_feat` | `Text`, `SkinQuery` | Artist text before a featuring separator. | `get_artist_before_feat` |
| `get_featuring_after_artist` | `Text`, `SkinQuery` | Featuring artist text stripped from the artist or title field. | `get_featuring_after_artist` |
| `get_artist_title_separator` | `Text`, `SkinQuery` | Dash separator when both artist and title are available. | `get_artist_title_separator` |
| `get_loaded_song_color` | `Text`, `SkinQuery` | Color of the loaded track, including color filters. | `get_loaded_song_color 'white'` |
| `has_cover` | `SkinQuery`, `Button` | True when cover art is available. | `has_cover` |
| `has_linked_tracks` | `SkinQuery`, `Button` | True when the track has links to other tracks. | `has_linked_tracks` |

Notes:

- `get_loaded_song_color` includes color filters; use `get_loaded_song color` when you specifically want the manually selected track color.
- `has_linked_tracks browsed` checks the browsed track; it can also take a script that returns a full file path.
- `get_featuring_after_artist` and `get_artist_title_separator` are useful for custom track-title layouts that need to rebuild VirtualDJ's artist/title/featuring formatting in separate text fields.

### Beatgrid And Position Queries

| Verb | Surfaces | Summary | Example |

| `get_beat_counter` | `Text`, `SkinQuery` | Current beat-counter position. | `get_beat_counter` |
| `get_beat_num` | `Text`, `SkinQuery` | Current beat number in the measure, or phrase-position query with parameters. | `get_beat_num 1` |
| `get_phrase_num` | `Text`, `SkinQuery` | Current measure number inside the phrase. | `get_phrase_num` |
| `get_bar` | `Text`, `SkinQuery` | Current bar number. | `get_bar` |
| `get_beat_bar` | `Text`, `SkinQuery` | Percentage position inside the bar. | `get_beat_bar 16` |

Notes:

- Use `get_beat` for a live beat-intensity value at the current position.
- Use `get_beatgrid` when the value should be tied to the beatgrid position: `100%` on beat, `0%` halfway between beats.

### Deck And Environment Queries

Notes:

- The 2026-06-30 appendix refresh confirmed `get_build`, `get_vdj_folder`, and `get_hwnd` as official environment queries.
- Treat `get_hwnd` as Windows-specific; prefer `get_build`, `get_version`, and `get_vdj_folder` for cross-platform diagnostic text.

### Input And Output Availability Queries

### Audio Analysis And Visualization Queries

| Verb | Surfaces | Summary | Example |
| --- | --- | --- | --- |
| `get_arm` | `Text`, `SkinQuery` | Position of the turntable arm. | `get_arm` |
| `get_peak_audio` | `Text`, `SkinQuery` | Peak audio helper for skin/system displays. | `get_peak_audio` |
| `get_spectrum_band` | `Text`, `SkinQuery` | Level of a single spectrum band. | `get_spectrum_band 1 32 vocals` |
| `get_volume` | `Text`, `SkinQuery` | Effective volume after volume sliders and crossfader. | `get_volume` |
| `get_deck_analysis` | `Text`, `SkinQuery` | Analysis helper for current or upcoming song events. | `get_deck_analysis` |
| `get_song_event` | `Text`, `SkinQuery` | Current or next song-event data for visualization plugins. | `get_song_event current volume` |
| `get_custom_text` | `Text`, `SkinQuery` | Custom text helper. | `get_custom_text` |

Notes:

- `get_spectrum_band` defaults to 32 bands; pass a second parameter for a different band count.
- The third `get_spectrum_band` parameter can request a stem-aware spectrum such as `vocals`.
- `get_song_event` accepts `current` or `next`, then an event field such as `hasbeats`, `volume`, `volume_end`, or `remaining`. `Local test` (2026-09-02, arg-form probe, `deck2_playing` fixture, each form read 3x): the two-token tail is confirmed and the selector defaults to `current` — `next volume` → `0.74` where `volume`, `current volume` and `volume_end` all → `1`, and `next hasbeats` → `no` where `hasbeats` → `yes`. A field alone works; a selector alone (`current`, `next`) is indistinguishable from nonsense, so the field is the required token and the selector the optional one.

| `keycue_pad_page` | `Pad`, `Text` | Change or query the key-cue pad page/window. | `keycue_pad_page` |
| `keycue_pad_jump` | `Pad`, `SkinAction` | Key-cue option for jumping to the cue while applying the key cue. | `keycue_pad_jump` |
| `get_timecode_quality` | `Text`, `SkinQuery` | Timecode signal quality helper. | `get_timecode_quality` |

Notes:

- The official Keycue pad page uses `keycue_pad <n>` as both pad action and backtick label, `keycue_pad_color <n>` for pad color, `keycue_pad_page` as Parameter 1, and `keycue_pad_jump` in the page menu.

### `get_browsed_song`

Aliases: none

Kind: `Query`

Typical surfaces: `Button`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Return a property from the currently browsed file

Typical forms:

```vdjscript
get_browsed_song 'title'
get_browsed_song 'type'
```

Preferred usage:

- pair with `param_equal` when branching on browsed-file metadata

Sources:

- `Official`: VDJScript verbs appendix

### `has_lyrics`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`, `Button`, `Pad`

Official summary:

- Return true when the song loaded on the deck has lyrics.

Typical forms:

```vdjscript
has_lyrics
deck 1 has_lyrics
has_lyrics ? edit_lyrics : nothing
```

Notes:

- This is deck-scoped. Do not assume it tests the browsed browser row.
- For browser filtering, use the browser/filter field such as the "Has Lyrics" instant filter.
- In skins, this is the safest styling hook for lyric availability badges.

Sources:

- `Official`: VDJScript verbs appendix
- `Official forum`: "Has Lyrics" browser filter quirks in VirtualDJ 2026 forum thread

### `get_lyrics_language`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`

Official summary:

- Return the language of the lyrics loaded on the deck.

Typical forms:

```vdjscript
get_lyrics_language
param_equal `get_lyrics_language` "en" ? action1 : action2
```

Notes:

- Good for a compact language chip or conditional color.
- It does not expose AI confidence, source, edited status, or translation details.

Sources:

- `Official`: VDJScript verbs appendix

### `edit_lyrics`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Open the Lyrics Editor for the track loaded on the deck.

Typical forms:

```vdjscript
edit_lyrics
```

Notes:

- The editor can be useful even when lyrics are missing or wrong, so do not automatically hide every editor control behind `has_lyrics`.
- There is no documented separate "reanalyze lyrics" verb in the checked sources; re-analysis is exposed in the editor UI.

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: Lyrics Editor manual

### `get_status`

Aliases: none

Kind: `Query`

Typical surfaces: `Text`, `SkinQuery`

Official summary:

- Return information about background tasks.

Typical forms:

```vdjscript
get_status
```

Notes:

- Probe this in the target build before displaying it. It may be useful for generic analysis/stems status, but no checked source guarantees a stable lyrics-specific status string.

Sources:

- `Official`: VDJScript verbs appendix

### `var_list`

Aliases: none

Kind: `Action`

Typical surfaces: `Button`, `Pad`, `Map`

Official summary:

- Show a window listing current variables and values.

Typical forms:

```vdjscript
var_list
```

Notes:

- A forum debugging pattern is to scatter temporary `set` calls through a complicated script, then inspect `var_list` to see which path ran.

Sources:

- `Official`: VDJScript verbs appendix
- `Community`: scripting-reference forum debugging guidance

### `load`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Load the selected song, or a specified full path, onto the deck

Typical forms:

```vdjscript

load "/path/to/file.mp3"
```

Sources:

- `Official`: VDJScript verbs appendix

### `play`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Start the deck

Typical forms:

```vdjscript
play
```

Sources:

- `Official`: VDJScript verbs appendix

### `play_stutter`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- If paused, start the deck. If playing, restart from the last stutter point.

Typical forms:

```vdjscript
play_stutter
```

Preferred usage:

- use when the control should deliberately retrigger from the stutter point
- for ordinary transport start behavior, prefer plain `play` or `play_pause`

Sources:

- `Official`: VDJScript verbs appendix

### `play_pause`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Start the deck if paused; pause it if playing

Typical forms:

```vdjscript
play_pause
```

Sources:

- `Official`: VDJScript verbs appendix

### `pause`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Pause the deck

Typical forms:

```vdjscript
pause
```

Sources:

- `Official`: VDJScript verbs appendix

### `stop`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Stop to the last cue point, then on second press to the beginning of the song, then cycle through the cue points

Typical forms:

```vdjscript
stop
```

Important note:

- This is not a simple synonym for `pause`.
- For deterministic documentation, spell out `stop`, `pause`, or `pause_stop` based on the behavior you actually want.

Sources:

- `Official`: VDJScript verbs appendix

### `cue_stop`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- If playing, pause and go to the last cue point. If paused, set the current position as cue and preview while pressed.

Typical forms:

```vdjscript
cue_stop
cue_stop 1
cue_stop 57
```

Sources:

- `Official`: VDJScript verbs appendix

### `pitch`

Aliases: `pitch2`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Set deck pitch

Typical forms:

```vdjscript
pitch +0.1%
pitch 112%
pitch 128bt
get_bpm & param_cast 'beats' & deck 2 pitch
param_multiply 1.333333 get_bpm & param_cast 'beats' & deck 2 pitch
```

Notes:

- `pitch <percent>` sets absolute playback speed, so `pitch 112%` means +12%.
- `pitch <number>` treats the value as pitch-slider position within the current `pitch_range`.
- `pitch <beats>` sets pitch so the deck matches the given BPM-like beats value. Adion's forum example is `pitch 128bt`.
- Use `param_cast 'beats'` when a math chain produces a numeric BPM value that should be consumed by `pitch` as a target BPM rather than as a pitch-slider value.
- This is useful for scripted tempo relationships: half/double logic, 3:4 transitions, and setting the opposite deck to a multiplier of the current deck's BPM.
- Example 3:4-up target: `param_multiply 1.333333 get_bpm & param_cast 'beats' & deck 2 pitch`.

### `pitch_reset`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Slowly bring the deck pitch back to zero/original speed

Typical forms:

```vdjscript
pitch_reset
pitch_reset 5%
pitch_reset 500ms
pitch_reset 4bt
```

Pad-page status pattern:

```xml
<pad13 name="RESET PITCH `get_text '%Ppitch%'`" autodim="false" color="loaded ? get_pitch_value &amp; param_bigger 125 ? color 'red' : get_pitch_value &amp; param_smaller 75 ? color 'red' : get_pitch_value &amp; param_bigger 105 ? color 'yellow' : get_pitch_value &amp; param_smaller 95 ? color 'yellow' : color 'green' : color 'black'" query="loaded ? get_pitch_value &amp; param_bigger 125 ? blink 500ms : get_pitch_value &amp; param_smaller 75 ? blink 500ms : on : off">pitch_reset 4bt</pad13>
```

Notes:

- For `get_pitch_value` comparisons in pad-page XML, use bare numeric thresholds such as `125`, `75`, `105`, and `95`.
- Do not write these thresholds as `125%` / `75%` in this pattern; local testing showed that can make the red branch match incorrectly.
- Keep colors in `color=""` and blink state in `query=""`.

Sources:

- `Official`: VDJScript verbs appendix
- `Local test`: 16-pad reset-pitch pad XML

### `get_pitch`

Aliases: none

Kind: `Query`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Return the current deck pitch value

Typical forms:

```vdjscript
get_pitch
get_pitch & param_multiply -1
```

Full pad-page reset pattern with inverse-pitch label:

```xml
<pad13 name="`get_pitch_zero ? get_text 'RESET BPM (0%)' : get_pitch &amp; param_smaller 0 ? get_text 'RESET BPM (+`get_pitch &amp; param_multiply -1`%)' : get_text 'RESET BPM (-`get_pitch`%)'`" autodim="false" color="loaded ? get_pitch_value &amp; param_bigger 125 ? color 'red' : get_pitch_value &amp; param_smaller 75 ? color 'red' : get_pitch_value &amp; param_bigger 105 ? color 'yellow' : get_pitch_value &amp; param_smaller 95 ? color 'yellow' : color 'green' : color 'black'" query="loaded ? get_pitch_value &amp; param_bigger 125 ? blink 500ms : get_pitch_value &amp; param_smaller 75 ? blink 500ms : on : off">pitch_reset 4bt</pad13>
```

This displays the inverse pitch with an explicit positive sign when needed:

```text
get_pitch = +18   -> RESET BPM (-18%)
get_pitch = -15.7 -> RESET BPM (+15.7%)
get_pitch = 0     -> RESET BPM (0%)
```

Notes:

- `get_pitch` returns pitch points suitable for display/math such as `18` or `15.7`; it is not a normalized decimal ratio.
- Do not run `get_pitch & param_cast "percentage"` when you only want a pitch label. Local pad-label testing showed it scales the value again, producing outputs such as `2146%` or `-2018.45%`.
- `get_pitch & param_multiply -1` flips the numeric sign, but it will not add a visible `+` for positive results and can display `-0`; use a separate sign expression and `get_pitch_zero` when the label must be polished.
- In pad page XML and skin XML attributes, write chain separators as `&amp;`; raw `&` is only for plain VDJScript outside XML.

### `get_pitch_value`

Aliases: none

Kind: `Query`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinQuery`, `Text`

Official summary:

- Return pitch on a `0` to `200` scale, centered on `100` for original speed

Typical forms:

```vdjscript
get_pitch_value
get_pitch_value & param_bigger 125 ? action1 : action2
get_pitch_value & param_smaller 75 ? action1 : action2
```

Preferred usage:

- Use `get_pitch_value` rather than raw BPM math when the question is "how far is this deck from the track's original tempo?"
- In pad-page XML comparisons, pair it with bare numeric thresholds and escape `&` as `&amp;`.

Sources:

- `Official`: VDJScript verbs appendix
- `Local test`: 16-pad reset-pitch pad XML

### `pad_page`

Aliases: `pad_pages`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Activate a pad page, override a page slot, or show the pad-page selector menu

Typical forms:

```vdjscript
pad_page 1
pad_page 1 hotcues
pad_page btn1
pad_page
```

Preferred usage:

- use the canonical singular name `pad_page` in docs
- call out `pad_pages` as the official alias for searchability

Sources:

- `Official`: VDJScript verbs appendix

### `filter`

Aliases: `filter_slider`

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Apply the selected ColorFX to the sound; nothing is applied at `50%`, and more is applied the farther from center

Typical forms:

```vdjscript
filter
filter 50%
filter 75%
down ? filter 75% : filter 50%
```

Preferred usage:

- for the main deck filter path, pair it with `filter_selectcolorfx`
- document `50%` as neutral; do not normalize docs around `0%` as if it were the center-off value

Sources:

- `Official`: VDJScript verbs appendix

### `filter_selectcolorfx`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Select the ColorFX controlled by the filter knob

Typical forms:

```vdjscript
filter_selectcolorfx 'Echo'
filter_selectcolorfx +1
filter_selectcolorfx -1
```

Preferred usage:

- use this as the main documented way to choose the deck's ColorFX
- prefer it over ad-hoc `effect_show_gui 'colorfx'` workflows when the goal is simply to set the selected ColorFX
- do not use this inside pad XML `query=""` for selected-state checks; use `filter_label 'name'` and `param_equal` so the query stays read-only

Quirk:

- CTO Adion explicitly recommends `filter_selectcolorfx` to avoid duplicated filter states when switching ColorFX/filter behaviors.

Sources:

- `Official`: VDJScript verbs appendix
- `Official forum`: "Default filter and color fx filter", Adion, 2023-05-19

### `filter_label`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`, `Button`, `Pad`

Official summary:

- Return the label shown under the filter knob

Typical forms:

```vdjscript
filter_label
filter_label 'clean'
filter_label 'name'
```

Preferred usage:

- use `filter_label 'name'` when you specifically want the ColorFX name rather than the value-style label
- pair with `param_equal` in pad XML `query=""` when you need to test which ColorFX is currently selected

Sources:

- `Official`: VDJScript verbs appendix

### `filter_resonance`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`

Official summary:

- Change the filter resonance

Typical forms:

```vdjscript
filter_resonance 50%
filter_resonance +5%
filter_resonance -5%
```

Preferred usage:

- use for live control of resonance
- use `setting 'filterDefaultResonance' ...` when what you really want is the program setting, not a one-off movement

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: options list
- `Official forum`: filter resonance discussion in the ColorFX/filter thread

### `effect_select`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Select an effect in a slot and deactivate the previous effect in that slot

Typical forms:

```vdjscript
effect_select 1 "echo"
effect_select 1 -1
effect_select +1
effect_select 1 0.2
effect_select 'vocals' 'reverb'
effect_select 'bass' 'echo'
```

Preferred usage:

- use slot-based effect selection for deterministic pad pages and skins
- prefer this over name-only global assumptions when you care which slot owns the effect
- treat `effect_select` as a write to slot state. For user-facing FX1-FX6 rack controls that should respect the performer's saved rack, prefer `effect_active <slot>`, `effect_slider <slot> ...`, and `effect_button <slot> ...` without selecting a new effect.
- for pad pages that intentionally own/reprogram a deck FX slot, pair `effect_select <slot> '<name>'` with explicit `effect_slider <slot> ...` values before activating the slot
- `effect_select` and `effect_active` do not provide a known `padfx`-style inline parameter list. For persistent slot FX, write an explicit chain such as `effect_select 1 'cut' & effect_slider 1 1 90% & effect_slider 1 2 0.5bt & effect_slider 1 3 50% & effect_active 1 on`.
- do not use bare `effect_select <slot>` as a harmless selected-name query in pad actions; it can open the effect selector. Use `get_effect_name <slot>` for labels and state checks.
- use `effect_select_multi <slot> '<name>'` instead when the pad should add/keep multiple effects in the same slot rather than replacing the previous effect
- `<slot>` can be a normal numeric deck FX slot or a supported special/named slot. Official forum guidance documents stem FX slot names such as `rhythm` and `vocals`; use these when the effect instance should live on a stem-specific slot rather than on numeric slots 1/2/3.
- current known named stem FX slots are `vocals`, `bass`, `instru`, `rhythm`, `melody`, `hihat`, and `kick`
- the vocal stem FX slot is `vocals` in the forum examples, while `padfx` stem targets use `stemfx:vocal`
- `melovocal` and `melorhythm` may exist as named stem FX slots, but need local testing before being treated as confirmed
- a local stem-slot pad pattern uses `effect_select 'vocals' 'reverb' ? effect_active 'vocals' : off` as the selected-and-active query; keep the numeric-slot `get_effect_name <slot>` guidance for ordinary rack slots
- do not rely on numeric slots above 6 or named stem FX slots as restart-persistent storage for the loaded effect. User-provided local observation on 2026-06-01 found that FX1-FX6 kept their loaded effect across a VirtualDJ restart, while FX7 and higher plus named stem slots such as `vocals` and `rhythm` kept their loaded effect only during the current session/across track loads and reset after restart.

### `effect_select_multi`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Select an effect in a slot while keeping the previous effect in that slot

Typical forms:

```vdjscript
effect_select_multi 1 "echo out"
effect_select_multi 1 "reverb"
effect_select_multi 'vocals' 'echo out'
effect_select_multi 'vocals' 'reverb'
```

Preferred usage:

- use when several effect instances should share a single numeric slot or named stem FX slot
- pair with `effect_active <slot> '<effect>'` so each pad toggles/queries the specific effect instance rather than only the slot as a whole
- add `on` or `off` to `effect_active` when you need deterministic state instead of toggle behavior
- for normal replacement/preset behavior, keep using `effect_select`; `effect_select_multi` is specifically for the multi-effect-per-slot selector behavior seen in the FX selection screen
- the same pattern works with the named vocal stem FX slot: `effect_select_multi 'vocals' 'echo out' & effect_active 'vocals' 'echo out'`
- this is distinct from `padfx ... 'stemfx:vocal'`, which triggers a pad effect on the vocal stem without using the named `vocals` stem FX slot as an ordinary `effect_*` target

Pad XML pattern:

```xml
<pad name="FX-VOCALS\nECHO OUT"
     color="stem_color 'vocal'"
     query="effect_active 'vocals' 'echo out'">
  effect_select_multi 'vocals' 'echo out' &amp; effect_active 'vocals' 'echo out'
</pad>
<pad name="FX-VOCALS\nREVERB"
     color="stem_color 'vocal'"
     query="effect_active 'vocals' 'reverb'">
  effect_select_multi 'vocals' 'reverb' &amp; effect_active 'vocals' 'reverb'
</pad>
```

### `effect_active`

Aliases: `effect_activate`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`

Official summary:

- Activate or deactivate the effect on a specific slot

Typical forms:

```vdjscript
effect_active 1
effect_active 1 on
effect_active 1 off
effect_active 1 'flanger' on
effect_active 'vocals'
effect_active 'vocals' 'echo' on
effect_active 'vocals' 'reverb'
```

Preferred usage:

- keep docs slot-centric when describing normal deck FX behavior
- mention the alias, but keep `effect_active` as canonical
- name-based forms such as `effect_active 'echo'` are valid shortcuts, but reference pad pages should use slots when they need predictable LED state and parameter ownership
- if a pad label names a specific effect, query both `get_effect_name <slot>` and `effect_active <slot>` so a different active effect in the same slot does not light the wrong pad
- turn a slot effect off with `effect_active <slot> off`
- for same-pad preset toggles, query `get_effect_name <slot>` first, then nest `effect_active <slot>` so pressing the same active effect turns the slot off while pressing a different effect loads/sets/activates it
- `&&` is documented for query chains, but use nested conditionals for action branches that combine effect-name checks, `? :`, and load/set/on side effects
- named stem FX slots can be activated with the same verb family, for example `effect_active 'vocals'` after loading a vocal-only Reverb into the `vocals` slot
- when `effect_select_multi` keeps several effect instances in one slot, include the effect name to query/toggle one instance, for example `effect_active 1 'echo out'` or `effect_active 'vocals' 'reverb'`
- use the effect-name form for per-pad LED/query state on shared slots. A slot-wide query such as `effect_active 'vocals'` can describe the stem slot as a whole, not which named effect in that slot is active.

- `Local test`: user-provided multi-effect vocal stem slot pad XML using `effect_active 'vocals' '<effect>'` for separate pad query/toggle state; build not recorded

### `effect_slider`

Aliases: `effect_slider_slider`

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Move a specific slider on the effect loaded in a given slot

Typical forms:

```vdjscript
effect_slider 1 2 50%
effect_slider 1 0%
effect_slider 'vocals' 1 50%
effect_slider 'vocals' 'echo' 1
effect_slider 'vocals' 'echo' 1 50%
```

Preferred usage:

- use explicit slot and slider numbers in docs and examples
- pair with `effect_select` and `effect_active` for deterministic FX presets
- avoid setting sliders by effect name in reference examples unless the example intentionally targets any active instance of that named effect
- for a named stem FX slot, the first parameter is the stem slot instead of a numeric slot. Community examples also show an effect-name parameter between the stem slot and slider number, for example `effect_slider 'Vocals' 'Echo' 1 50%`.
- at least one forum follow-up reported that only the GUI form worked in that user's setup; test stem-slot slider forms on the target build before treating them as canonical for a controller or skin

### `effect_colorfx`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Select an effect for one of up to four custom ColorFX slots

Typical forms:

```vdjscript
effect_colorfx 1 "echo"
```

Preferred usage:

- use when building extra ColorFX-like controls that should not hijack the main deck filter path

Quirk:

- This is not the same thing as selecting the standard deck filter ColorFX. For that, prefer `filter_selectcolorfx`.

Sources:

- `Official`: VDJScript verbs appendix
- `Official forum`: ColorFX/filter guidance from staff and CTO posts

### `effect_colorslider`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Control an effect from a center-off position to full on left or right

Typical forms:

```vdjscript
effect_colorslider 1
```

Preferred usage:

- pair it with `effect_colorfx` for custom ColorFX-style controls

Sources:

- `Official`: VDJScript verbs appendix

### `colorfx_slider`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Adjust the ColorFX parameter

Typical forms:

```vdjscript
colorfx_slider
colorfx_slider 50%
```

Preferred usage:

- use `filter` for the normal deck filter / selected ColorFX amount path
- use `colorfx_slider` when mapping a dedicated ColorFX parameter control exposed by a controller or skin

Sources:

- `Official`: VDJScript verbs appendix

### `effect_releaseslider`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `SkinAction`

Official summary:

- Control the effect release-specific slider

Typical forms:

```vdjscript
effect_releaseslider
effect_releaseslider 50%
```

Preferred usage:

- treat this as a release-FX-specific control path, separate from normal slot sliders
- use `is_releasefx` when the UI needs to know whether the current effect is in the release-FX slot

Sources:

- `Official`: VDJScript verbs appendix

### `effect_releaseslider_active`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `SkinAction`

Official summary:

- Control the effect release-specific slider and automatically activate the effect

Typical forms:

```vdjscript
effect_releaseslider_active
effect_releaseslider_active 50%
```

Preferred usage:

- use for momentary-style release-FX controls that should activate while the slider is being moved
- keep normal effect-slot controls on `effect_slider` / `effect_slider_active`

Sources:

- `Official`: VDJScript verbs appendix

### `effect_stems`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Apply effects only to selected stems

Typical forms:

```vdjscript
effect_stems vocal on
effect_stems 'melody'
effect_stems off
effect_stems ? on : off
```

Preferred usage:

- use when a pad page or skin intentionally routes audio FX to part of the track instead of the full deck signal
- use `effect_stems off` to return FX routing to the full track
- in skin and pad state, query `effect_stems '<stem>'` when you need a specific route and query bare `effect_stems` when any stem-FX route should count as active
- this is shared FX routing, not the same thing as a separate named stem FX slot such as `vocals`
- when you need an independent effect instance for a stem, use a stem FX slot with the `effect_*` verbs or `padfx ... 'stemfx:<stem>'`

Notes:

- Official stem names are `Vocal`, `HiHat`, `Bass`, `Instru`, `Kick`, `Melody`, `Rhythm`, `MeloVocal`, and `MeloRhythm`.
- Existing local pad pages use lowercase names such as `vocal`, `melody`, and `rhythm`; keep that style when matching nearby pad XML.

Sources:

- `Official`: VDJScript verbs appendix
- `Official forum`: "BUILD 7403 - Multiple stems fx can be used at the same time?", Adion, 2023-01-15
- `Local test`: existing pad pages in this repo use `effect_stems` for ColorFX / push-FX routing

### `effect_stems_color`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`, `Pad`

Official summary:

- Return the color for the `effect_stems` button

Typical forms:

```vdjscript
effect_stems_color
```

Preferred usage:

- use for a generic "FX to stems" indicator when the UI should follow VirtualDJ's own stems-FX color
- use `stem_color '<stem>'` instead when a control is explicitly tied to one stem

Sources:

- `Official`: VDJScript verbs appendix

### `stem_color`

Aliases: none

Kind: `Query`

Typical surfaces: `SkinQuery`, `Text`, `Pad`

Official summary:

- Return the default color of a specific stem

Typical forms:

```vdjscript
stem_color 'Vocal'
stem_color 'Melody'
stem_color 'Rhythm'
```

Preferred usage:

- use for per-stem pad colors and skin indicators
- use `effect_stems_color` for a generic effect-stems button color that should follow VirtualDJ's own `effect_stems` state

Sources:

- `Official`: VDJScript verbs appendix

### `stems_bleed`

Aliases: none

Kind: `Dual`

Typical surfaces: `Pad`, `Button`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Adjust or query the stems bleed control when the loaded track has compatible stems

Typical forms:

```vdjscript
stems_bleed
has_stems '1.0' ? stems_bleed : nothing
`has_stems '1.0' ? stems_bleed : has_stems 'ready'`
```

Preferred usage:

- expose it behind a guarded stem-control parameter so decks without 1.0 stems can fall back to `has_stems 'ready'`

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: `examples/Pads/Built-In/pads_stems.xml`

### `effect_arm_stem`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `SkinAction`

Official summary:

- Select or unselect a stem to be used with `stems` as the slot for `effect_*` actions

Typical forms:

```vdjscript
effect_arm_stem Vocal
effect_arm_stem Vocal+Bass
effect_arm_stem Vocal & effect_select 'stems' 'Echo' & effect_active 'stems'
```

Preferred usage:

- use for controller mappings that expose a stem-selection layer before operating on effect actions
- use `effect_stems` for ordinary pad-page or skin controls that directly route current deck effects to stems
- the official appendix describes `effect_arm_stem` as selecting stems for the special `stems` slot used by `effect_*` actions
- do not confuse this `stems` aggregate slot with named stem FX slots such as `vocals`; both are slot-like effect targets, but they are selected differently

Sources:

- `Official`: VDJScript verbs appendix

### `effect_bpm_deck`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Set or get a custom BPM for plugins activated on this deck

Typical forms:

```vdjscript
effect_bpm_deck 120
effect_bpm_deck off
effect_bpm_deck
```

Preferred usage:

- use only when an effect plugin should run against a custom BPM that differs from the loaded song
- reset with `effect_bpm_deck off` to return plugins to the song BPM

Sources:

- `Official`: VDJScript verbs appendix

### `effect_bpm_deck_tap`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `SkinAction`

Official summary:

- Tap a custom BPM for plugins activated on this deck

Typical forms:

```vdjscript
effect_bpm_deck_tap
effect_bpm_deck off
```

Preferred usage:

- use for hardware or skin tap controls that set effect-plugin BPM independently of the song BPM
- pair with `effect_bpm_deck off` as the reset affordance

### Armed FX Helpers

These verbs are primarily for controllers with deck/effect selection switches. They build an intermediate "armed" target, then `effect_arm_active` activates the selected effect on the selected deck.

| Verb | Kind | Summary | Example |
| --- | --- | --- | --- |
| `effect_arm_deck` | `Action` | Select the deck, master, sampler, mic, or aux target for armed FX. | `effect_arm_deck master` |
| `effect_arm_select` | `Action` | Select the effect that `effect_arm_active` will activate. | `effect_arm_select 'echo'` |
| `effect_arm_select_popup` | `Action` | Open/select from the armed-effect selection popup. | `effect_arm_select_popup` |
| `effect_arm_slot` | `Action` | Toggle whether a slot is activated by `effect_arm_active`. | `effect_arm_slot 1` |
| `effect_arm_active` | `Dual` | Activate the armed effect on the armed deck. | `effect_arm_active` |
| `effect_arm_slider` | `Action` | Move a parameter for the armed effect/deck selection. | `effect_arm_slider 1 2` |
| `effect_arm_slider_name` | `Text` | Return a parameter name for the armed effect/deck selection. | `effect_arm_slider_name 1 short` |
| `effect_arm_slider_text` | `Text` | Return parameter value text for the armed effect/deck selection. | `effect_arm_slider_text 1` |
| `effect_arm_slider_label` | `Text` | Return a parameter label for the armed effect/deck selection. | `effect_arm_slider_label 1 short` |
| `effect_arm_beats` | `Action` | Change the speed of the armed effect/deck selection. | `effect_arm_beats 1` |
| `effect_arm_bpm` | `Text` | Return the BPM of the deck selected by `effect_arm_deck`. | `effect_arm_bpm` |

Notes:

- `effect_arm_deck single` limits arming to one deck at a time.
- `effect_arm_deck master`, `effect_arm_deck sampler`, `effect_arm_deck mic`, and `effect_arm_deck aux` target non-deck effect paths.
- Prefer direct slot verbs such as `effect_select`, `effect_slider`, and `effect_active` in skins and pad pages unless you are intentionally modeling a hardware armed-FX workflow.

### FX Send/Return Helpers

These verbs are for hardware-style FX send/return routing. The official appendix currently gives detailed examples for the multi-source selector and lists the other two names with minimal description.

| Verb | Kind | Summary | Example |
| --- | --- | --- | --- |
| `effect_fxsendreturndeck` | `Action` | Select the source deck for an FX send/return path. | `deck 1 effect_fxsendreturndeck` |
| `effect_fxsendreturndeck_multi` | `Action` | Select which source to apply FX to for a specific send/return channel when multiple channels exist. | `deck 2 effect_fxsendreturndeck_multi mic` |
| `effect_fxsendreturnenable` | `Dual` | Enable or query the FX send/return path. | `effect_fxsendreturnenable` |

Examples:

```vdjscript
deck 1 effect_fxsendreturndeck_multi master
deck 2 effect_fxsendreturndeck_multi mic
deck 2 effect_fxsendreturndeck_multi 4
```

- `Official`: VDJScript verbs appendix

### `effect_mixfx`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Associate an effect with the crossfader

Typical forms:

```vdjscript
effect_mixfx
```

Preferred usage:

- use `effect_mixfx_select` when the goal is to choose a specific Mix FX by name
- use `effect_mixfx_activate` when the goal is to toggle Mix FX on/off

Notes:

- Community/forum guidance describes Mix FX as applying an effect to both decks with strength linked to crossfader movement.
- Older forum examples sometimes discuss Mix FX under the name "Mix Assist"; document both terms in prose for searchability.

Sources:

- `Official`: current VDJScript verbs appendix
- `Official forum`: "Mix Assist in other skins", staff context for crossfader-linked behavior
- `Community`: Mix FX examples from forum users and moderators
- `Published skin`: the former local `Haunting Pro Edit/Touch.xml` capture used `effect_mixfx`

### `effect_mixfx_activate`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`

Official summary:

- Toggle Mix FX on or off; use `effect_mixfx_select` to choose the Mix FX

Typical forms:

```vdjscript
effect_mixfx_activate
effect_mixfx_activate ? on : off
effect_mixfx_select 'echo' & effect_mixfx_activate
```

Preferred usage:

- use as the Mix FX on/off state, not as the effect selector
- pair with `effect_mixfx_select '<name>'` when building a named Mix FX button

Quirks:

- A 2019 forum test reports that `effect_mixfx_activate '<name>'` behaves as a global on/off query rather than selecting or querying that named Mix FX. Keep that form out of examples until locally retested.
- The Denon Prime 4 Deluxe skin uses `effect_mixfx_activate & effect_mixfx_select 'FILTER'` for named buttons. A local 2026 test confirmed direct selected-state queries for `effect_mixfx_select`, but did not retest order-dependent activation behavior, so keep `effect_mixfx_select '<name>' & effect_mixfx_activate` as the clearer example order.

### `effect_mixfx_select`

Aliases: none

Kind: `Dual`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Select the Mix FX used when moving the crossfader

Typical forms:

```vdjscript
effect_mixfx_select
effect_mixfx_select 'filter'
effect_mixfx_select 'filter' ? on : off
param_equal "`effect_mixfx_select`" "filter" ? on : off
```

Preferred usage:

- use the parameter form to select a named Mix FX
- use the no-parameter form as a display/query value for the currently selected Mix FX
- use direct `effect_mixfx_select '<name>' ? ...` for named selected-state tests in current VirtualDJ pad pages and skins
- keep the indirect `param_equal "\`effect_mixfx_select\`" "<name>" ? ...` form when comparing the returned display value or documenting older-build-compatible examples

Runnable pad XML example:

```xml
<pad1 name="DIRECT FILTER"
      color="effect_mixfx_select 'FILTER' ? color '#31D67B' : color '#7A3038'"
      query="effect_mixfx_select 'FILTER' ? on : off">
  effect_mixfx_select 'FILTER'
</pad1>
<pad2 name="INDIRECT FILTER"
      color="param_equal &quot;`effect_mixfx_select`&quot; &quot;FILTER&quot; ? color '#31D67B' : color '#7A3038'"
      query="param_equal &quot;`effect_mixfx_select`&quot; &quot;FILTER&quot; ? on : off">
  effect_mixfx_select 'FILTER'
</pad2>
```

Minimal skin query fragment:

```xml
<button x="0" y="0"
        action="effect_mixfx_select 'FILTER'"
        query="effect_mixfx_select 'FILTER' ? on : off">
  <size width="120" height="32"/>
  <off shape="square" color="#6E2F35"/>
  <on shape="square" color="#1E8E5A"/>
  <text text="FILTER" color="#FFFFFF" align="center"/>
</button>
<panel visibility="param_equal &quot;`effect_mixfx_select`&quot; &quot;FILTER&quot; ? true : false">
  <square color="#1E8E5A">
    <pos x="0" y="40"/>
    <size width="120" height="32"/>
  </square>
</panel>
```

Quirks:

- Older forum testing reported that direct queries such as `effect_mixfx_select 'echo' ? ...` did not return reliable boolean results in pad-page logic. A local test on VirtualDJ 8.5.9307 / 850.9336.mac.2224 confirmed direct and indirect queries both work in pad XML `query`/`color`, skin button `query`, and skin `visibility` contexts.
- The no-parameter display form returned lowercase names such as `filter` and `echo` in the local test, while `param_equal` still matched uppercase comparison strings such as `FILTER` and `ECHO`.
- The Denon Prime 4 Deluxe skin uses direct skin queries such as `effect_mixfx_select 'FILTER' ? effect_mixfx_activate`; current local skin testing is consistent with that selected-state query pattern.

### `effect_show_gui`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Show the control window for an effect

Typical forms:

```vdjscript
effect_show_gui 1
effect_show_gui 'colorfx'
effect_show_gui 'rhythm' 'Beat Grid'
effect_show_gui 'vocals' 'echo'
```

Notes:

- Treat GUI access as separate from canonical selection logic. Opening a GUI does not make it the preferred API path for selection or activation.
- Adion documented `effect_show_gui "rhythm" "Beat Grid"` for showing a padfx GUI for a specific stem set, and said the same syntax can be used with other `effect_*` actions.
- Community examples also use `effect_show_gui vocals echo` as a diagnostic helper for checking whether a vocal stem effect instance is actually opening/activating.

### `sampler_play`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Play the default sample or a specified absolute sample slot

Typical forms:

```vdjscript
sampler_play
sampler_play 4
```

Preferred usage:

- use for absolute-slot sampler control

Sources:

- `Official`: VDJScript verbs appendix

### `sampler_stop`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Stop one sample or all playing samples

Typical forms:

```vdjscript
sampler_stop 4
sampler_stop all
```

Preferred usage:

- use for absolute-slot stop logic or global cleanup actions

Sources:

- `Official`: VDJScript verbs appendix

### `sampler_pad`

Aliases: none

Kind: `Dual`

Typical surfaces: `Pad`, `Button`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Trigger the sample in the visible sampler pad position; in display contexts it can also return the visible pad label

Typical forms:

```vdjscript
sampler_pad 1
sampler_pad 1 "auto"
`sampler_pad 1`
```

Preferred usage:

- use this for page-aware sampler UI, not fixed absolute slot control

Quirk:

- In display contexts, `sampler_pad <n>` is often the safest way to show the visible sample label on the current page.

### `sampler_pad_page`

Aliases: none

Kind: `Dual`

Typical surfaces: `Pad`, `Button`, `SkinAction`, `SkinQuery`, `Text`

Official summary:

- Change or query the current 8-pad sampler window

Typical forms:

```vdjscript
sampler_pad_page +1
sampler_pad_page -1
sampler_pad_page
```

Preferred usage:

- treat this as the official pager behind sampler `1-8`, `9-16`, `17-24`, and later windows
- local pad/skin tests observed query output as text ranges such as `"1 to 8"` and `"9 to 16"`, so branch with `param_equal "9 to 16"` rather than numeric page indexes unless the target build has been verified

### `sampler_velocity`

Aliases: none

Kind: `Query`

Typical surfaces: `Pad`, `SkinQuery`

Official summary:

- Return the velocity/pressure value for a sampler pad slot

Typical forms:

```vdjscript
sampler_velocity 1
```

Preferred usage:

- use in pad XML `pressure=""` on velocity-sensitive sampler pages, paired with the matching `sampler_pad <n> "auto"` trigger

```xml
<pad1 pressure="sampler_velocity 1">sampler_pad 1 "auto"</pad1>
```

Sources:

- `Official`: VDJScript verbs appendix
- `Official`: `examples/Pads/Built-In/pads_sampler_velocity.xml`

### `sampler_assign`

Aliases: none

Kind: `Action`

Typical surfaces: `Pad`, `Map`, `Button`, `SkinAction`

Official summary:

- Assign a `.vdjsample` file to a slot

Typical forms:

```vdjscript
sampler_assign 1 "/Samples/horn.vdjsample"
```

Preferred usage:

- use for explicit slot assignment when the destination slot is known
- on custom pad pages, pair it with pad XML `drop=` to accept dragged files:

```xml
<pad1 drop="sampler_assign 1">...</pad1>
```

Quirk:

- treat the target slot as absolute unless you have build-specific proof otherwise. The current official docs show fixed slot numbers and do not document a page-aware `"auto"` form for `sampler_assign`.
- The current stock/local sampler page in this repo uses `drop="sampler_assign <slot>"`; see [SAMPLER SIMPLE.xml](../examples/Pads/Quarantine/SAMPLER%20SIMPLE.xml).

### `sampler_loaded`

Aliases: none

Kind: `Query`

Typical surfaces: `Pad`, `SkinQuery`, `Text`

Official summary:

- Return true when a sample is loaded in the target slot

Typical forms:

```vdjscript
sampler_loaded 1
```

Quirk:

- The manual explicitly documents fixed-slot behavior.
- Forum examples use quoted `sampler_loaded <n> "auto"`, and the installed/public `Loop Recorder.xml` pad page uses unquoted `sampler_loaded <n> auto`, but neither form is documented in the official verbs appendix.
- Local testing on VirtualDJ 8.5.9307 / 18.0.9336 showed both `sampler_loaded 8 "auto"` and `sampler_loaded 8 auto` still checking absolute slot 8 while visible pad 8 on sampler page 2 mapped to slot 16. In other words: do not rely on `auto`, quoted or unquoted, for page-aware empty-slot checks.
- For paged sampler UI, guard visible pads with the calculated absolute slot for the current `sampler_pad_page` (`sampler_loaded 16` for page 2 pad 8), while still using `sampler_pad 8` for the visible pad action/label.
- **`all` means the SELECTED slot, not every slot** (`Local test`, 2026-09-03, fixture
  `sampler_slots_differ` — slots 1-5 hold different samples, 6-8 are empty). With slot 1
  selected, `get_sample_name all` returned `'Dystopia Breaks'` and `sampler_color all`
  `#4D94F6`, both slot 1's values; after `sampler_select 5` the same two queries returned
  `'SB_IR&D_RISERS_140_093'` and `white`, matching slot 5 exactly. So `all` follows the
  selection rather than aggregating. `sampler_loaded all` stayed `yes` throughout while
  `sampler_loaded 8` was `no`, which rules out "every slot" independently. This resolves the
  question left open on 2026-09-02, when no fixture could tell "any", "first" and "every" apart.
- `sampler_select` takes a **1-based slot number on execute** but answers a **normalized 0-1
  slider value on query**: `sampler_select 5` selects slot 5 and then reads back `1`, and
  `sampler_select 1` selects slot 1 and reads back `0`. Do not feed its query value back into
  it as a slot number.
- **`all` is a reserved tail token across the sampler family** — `Local test` (2026-09-02, shared-lexicon probe plus direct queries): 22 verbs treat `all` differently from an arbitrary token, including `sampler_loaded`, `sampler_color`, `sampler_select`, `sampler_position`, `sampler_play`/`_stop`/`_play_stop`/`_play_stutter`, `sampler_default`, `sampler_load_to_deck`, the four `get_sample_*` queries, `loop_load`, `loop_select`, `load_skin`, `load_pulse`, `effect_stems`, `effect_dock_gui` and `apply_audio_config`. **What it does is not established.** In every fixture tested `<verb> all` returned exactly the bare value while nonsense errored or read `no`, so the probe proves the parser reserves the word and nothing more; on `loop_load`, `loop_select`, `load_skin` and `load_pulse` it inverts — `all` returns `E_INVALIDARG` where an arbitrary token is accepted as a name, so there the word is reserved for a form taking different arguments. Establishing meaning needs a state where slots disagree (several sampler slots loaded with different values), which no current fixture builds.
- Follow-up (2026-09-03) narrows it. `all` is **not** sampler-specific vocabulary: it is a target keyword, and query context collapses it to the first member rather than aggregating — exactly as [`deck all`](VDJScript%20Grammar.md#deck-all-broadcasts-on-execute-and-collapses-to-one-deck-on-query) does. With slots 1-5 loaded and 6-8 empty, `sampler_loaded all` reads `yes` and `get_sample_name all` returns slot 1's name, both identical to bare. `active` is accepted alongside it on the sampler verbs (`sampler_loaded active` -> `yes`, `get_sample_name active` -> slot 1's name) while the deck-only targets are not (`master`, `left`, `right`, `opposite` all read `no`). Verbs the probe did *not* flag ignore the tail entirely — `get_bpm all`, `get_bpm active` and `get_bpm zzqqx` all return the same value. Whether the sampler `all` broadcasts on execute the way `deck all` does is untested; it would write to five loaded slots.

Official summary:

- Return the sample color for the visible sampler pad slot

Typical forms:

```vdjscript
sampler_color 1

### Saved Loop Pad Helpers

| Verb | Kind | Surfaces | Summary | Example |
| --- | --- | --- | --- | --- |
| `saved_loop_display` | `Dual` | `Pad`, `Text`, `SkinQuery` | Display a saved-loop slot label or choose the saved-loop display mode. | `` `saved_loop_display 1` ``, `saved_loop_display 'length'` |
| `loop_color` | `Query` | `Pad`, `SkinQuery`, `Text` | Return the color for a saved-loop slot. | `loop_color 1` |
| `loop_delete` | `Action` | `Pad`, `SkinAction` | Delete a saved-loop slot. | `loop_delete 1` |
| `loop_load_prepare` | `Dual` | `Pad`, `SkinAction`, `SkinQuery` | Prepare/load a saved-loop slot and query whether that slot is prepared. | `loop_load 1 ? loop_load_prepare 1 : loop_save 1` |

Notes:

- The official Saved Loops pad page uses `loop_load_prepare <n>` as a query for blink state and as the action after an existing `loop_load <n>` test; holding a populated pad runs `loop_delete <n>`.

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`

Official summary:

- Smoothly synchronize the song with the other deck

Typical forms:

```vdjscript

Sources:

- `Official`: VDJScript verbs appendix

### `match_bpm`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Set the pitch to match the BPM of the other deck

```vdjscript
match_bpm
```

Sources:

- `Official`: VDJScript verbs appendix

### `play_sync`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Play the song instantly synchronized with the other deck

Typical forms:

```vdjscript
play_sync
```

Preferred usage:

- use when the action should both sync and start playback immediately
- do not confuse this with the `smart_play` setting/action

Sources:

- `Official`: VDJScript verbs appendix

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Instantly synchronize using local beat information instead of the global beatgrid

Preferred usage:

- call out the alias because older scripts and forum posts often reference `sync_nocbg`

Sources:

- `Official`: VDJScript verbs appendix

### `beatlock`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`, `SkinAction`, `SkinQuery`

Official summary:

- Keep songs synchronized even while moving pitch, scratching, and similar manipulations

Official summary:

- When enabled, songs are automatically synchronized when started

Typical forms:

```vdjscript
smart_play
smart_play on
smart_play off

Important note:

- This is a setting-like behavior toggle, not the same thing as the `play_sync` transport action.

Sources:

- `Official`: VDJScript verbs appendix

### `phrase_sync`

Aliases: none

Kind: `Action`

Typical surfaces: `Map`, `Button`, `Pad`

Official summary:

- Shift by a number of beats to match the phrase of the other deck

Typical forms:

```vdjscript
phrase_sync
phrase_sync 16
```

Notes:

- The beat-count argument must be a literal. A local test found that a backtick-interpolated/computed argument does **not** work here: neither `` phrase_sync '`$phrase_len`' `` nor the otherwise-documented `` phrase_sync `get_var '$phrase_len'` `` produced the expected result.
- This is not `phrase_sync`-specific: the grammar battery run on `v2026-m b9482` showed `loop` and `beatjump` also ignore backtick-computed arguments while the identical literals work. See Tested Grammar Rules in [VirtualDJ Reference](VirtualDJ%20Reference.md).
- To pick the count from a variable, branch to a literal instead of interpolating, e.g. `var_equal '$phrase_len' 16 ? phrase_sync 16 : phrase_sync 32`. See [VDJScript Local Test Tracker](VDJScript%20Local%20Test%20Tracker.md) (2026-07-05 and 2026-07-14 entries).

### Browser Folder And List Helpers

These actions create or modify browser folders, lists, and list shortcuts. Most are useful in skin buttons and controller mappings, but several are destructive enough to avoid wiring to accidental gestures.

| Verb | Aliases | Surfaces | Summary | Example |
| --- | --- | --- | --- | --- |
| `add_favoritefolder` | — | `Button`, `SkinAction` | Make the selected folder a favorite / monitored folder. | `add_favoritefolder` |
| `add_filterfolder` | — | `Button`, `SkinAction` | Create a new filter folder. | `add_filterfolder` |
| `add_to_list` | `virtualfolder_add` | `Button`, `SkinAction` | Add selected browser songs to the specified list. | `add_to_list 'Warmup'` |
| `create_list_from_playlist` | `create_virtualfolder_from_playlist` | `Button`, `SkinAction` | Save the automix playlist as a MyLists entry. | `create_list_from_playlist` |

Sources:

- `Official`: VDJScript verbs appendix

### Browser File Actions

These actions operate on the currently selected browser file or files, not necessarily the loaded deck.

| Verb | Surfaces | Summary | Example |
| --- | --- | --- | --- |
| `browsed_file_info` | `Button`, `SkinAction` | Open the Tag Editor for the browsed song. | `browsed_file_info` |
| `browsed_file_reveal` | `Button`, `SkinAction` | Reveal the browsed song in the OS file manager. | `browsed_file_reveal` |
| `browsed_file_reload_tag` | `Button`, `SkinAction` | Reload the selected file's tag from the source file. | `browsed_file_reload_tag` |
| `browsed_file_rename` | `Button`, `SkinAction` | Rename the selected browser file. | `browsed_file_rename` |
| `set_browsed_file_bpm` | `Button`, `SkinAction` | Set the BPM of selected browser songs. | `set_browsed_file_bpm 129.3` |
| `browsed_song` | `Button`, `SkinAction` | Set a property on the currently browsed file. | `browsed_song 'rating' 5` |
| `loaded_song` | `Button`, `SkinAction` | Set a property on the track loaded on the deck. | `loaded_song 'rating' 5` |
| `browsed_song_hashtag` | `Button`, `SkinAction` | Add or remove a hashtag from a browsed-song field. | `browsed_song_hashtag 'user 1' '#high_energy'` |
| `loaded_song_hashtag` | `Button`, `SkinAction` | Add or remove a hashtag from a loaded-song field. | `loaded_song_hashtag 'user 1' '#warmup'` |
| `edit_comment` | `Button`, `SkinAction` | Open a window to edit the selected track's comment. | `edit_comment` |

Important notes:

- `browsed_file_reload_tag` overwrites VirtualDJ database changes with values saved in the file tag.
- `set_browsed_file_bpm` follows the same value style as `set_bpm`, including absolute and relative values.
- Prefer `get_browsed_song` / `get_loaded_song` for read-only display; use `browsed_song` / `loaded_song` only when a control should write metadata.
- **In a query context `browsed_song <field> <value>` is an exact-match predicate**, not a getter: it answers `yes`/`no` on whether the browsed song's field equals the value. `Local test` (2026-09-02, arg-form probe plus direct HTTP queries, browsed track *In The Dark* by *Luke Alexander*): `browsed_song title 'In The Dark'` → `yes`, `browsed_song artist 'Luke Alexander'` → `yes`, `browsed_song title 'Not The Title'` → `no`, and the match is exact rather than substring — `browsed_song title 'In'` → `no`. An unknown field answers `no` rather than erroring (`browsed_song bogusfield 'In The Dark'` → `no`), so a typo reads as a mismatch and fails silently. **Both tokens are required**: every one-token form, `browsed_song title` included, returns `E_INVALIDARG`; use `get_browsed_song 'title'` to read a value.

| `has_linked_tracks` | `Query` | `SkinQuery`, `Button` | Check whether a track has linked/related tracks. | `has_linked_tracks browsed` |
| `page` | `Dual` | `Button`, `SkinAction`, `Text` | Browser/page helper from the official appendix. | `page` |

Skin pattern:

```vdjscript
browser_zoom ? true : browser_isactive ? true : false
```

This is useful when a skin has a browser-zoom or "mini deck" layout that should appear either when the browser is explicitly zoomed or when controller/browser focus is active.

Track relationship pattern:

```vdjscript
deck 1 loaded ? deck 2 loaded ? mark_linked_tracks : nothing
has_linked_tracks browsed ? sideview 'remixes' : nothing
```

Sources:

- `Official`: VDJScript verbs appendix
- `Local test`: working skin XML uses `browser_zoom` and `browser_isactive` in layout visibility queries
- `Inference`: the combined query pattern is a skin-layout convention built from those queries

Sources:

- `Official`: VDJScript verbs appendix
- `Built-in app resource`: Button Editor taxonomy has a visible `automix` category and includes `playlist_add` as an example; this supports grouping only, not detailed behavior.
- `Inference`: `automixDualDeck` in configuration options is the setting-side counterpart to `automix_dualdeck`.

Needs local test:

- `automix_editor_movetrack`: confirm accepted target tokens beyond `'current'` and whether the offset is item rows.
- `get_automix`, `get_automix_song`, `get_automix_position`, `get_playlist_time`: confirm return formats, empty-list behavior, and whether indexes are zero- or one-based where relevant.
- `playlist_add` and `playlist_load`: confirm selected-item scope, append/replace behavior, and whether folder versus playlist input differs.

### EQ

VirtualDJ's three-band EQ. Each band operates on the full deck signal.
Shipped skin XML treats EQ knobs as center-origin controls: `frommiddle="true"`, double-click reset to `eq_* 50%`, and right-click toggles between `eq_* 0%` and `eq_* 50%`.

| Canonical | Aliases | Surfaces | Description | Sources |
| --- | --- | --- | --- | --- |
| `eq_high` | — | `Map`, `SkinAction`, `SkinQuery` | Deck high-EQ control/query. Built-in skins bind it to center-origin sliders and reset with `eq_high 50%`. | `Official`, `Built-in skin` |
| `eq_mid` | `eq_med` | `Map`, `SkinAction`, `SkinQuery` | Deck mid-EQ control/query. Built-in skins bind it to center-origin sliders and reset with `eq_mid 50%`. | `Official`, `Built-in skin` |
| `eq_low` | — | `Map`, `SkinAction`, `SkinQuery` | Deck low-EQ control/query. Built-in skins bind it to center-origin sliders and reset with `eq_low 50%`. | `Official`, `Built-in skin` |
| `eq_kill_high` | — | `Map`, `SkinAction`, `SkinQuery` | Toggle/query high-band kill. Built-in skins use it as button/query state and label visibility state. | `Official`, `Built-in skin` |
| `eq_kill_mid` | `eq_kill_med` | `Map`, `SkinAction`, `SkinQuery` | Toggle/query mid-band kill. Built-in skins use it as button/query state and label visibility state. | `Official`, `Built-in skin` |
| `eq_kill_low` | — | `Map`, `SkinAction`, `SkinQuery` | Toggle/query low-band kill. Built-in skins use it as button/query state and label visibility state. | `Official`, `Built-in skin` |
| `eq_reset` | — | `Map`, `SkinAction` | Reset deck EQ bands. Built-in skins more often reset individual bands with `eq_* 50%`. | `Official`, `Built-in skin` |
| `eq_high_freq` | — | `Map`, `SkinAction` | Set the crossover frequency of the high band. | `Official` |
| `eq_mid_freq` | — | `Map`, `SkinAction` | Set the crossover frequency of the mid band. | `Official` |
| `eq_low_freq` | — | `Map`, `SkinAction` | Set the crossover frequency of the low band. | `Official` |
| `eq_high_slider` | — | `Map`, `SkinAction` | Controller/slider-oriented high-EQ form. For skins, shipped XML uses `eq_high` with `frommiddle="true"`. | `Official`, `Built-in skin` |
| `eq_mid_slider` | `eq_med_slider` | `Map`, `SkinAction` | Controller/slider-oriented mid-EQ form. For skins, shipped XML uses `eq_mid` with `frommiddle="true"`. | `Official`, `Built-in skin` |
| `eq_low_slider` | — | `Map`, `SkinAction` | Controller/slider-oriented low-EQ form. For skins, shipped XML uses `eq_low` with `frommiddle="true"`. | `Official`, `Built-in skin` |
| `eq_mode` | — | `Map`, `SkinAction` | Cycle or set EQ mode. Built-in skins use `eq_mode` and `eq_mode +1`; config docs list `frequency`, `modernEQ`, `ezRemix`, and `stems` as setting-side values. | `Official`, `Built-in skin`, `Inference` |
| `fake_eq` | — | `Map`, `SkinAction` | EQ that only affects the preview/headphone signal, not master output. | `Official` |

Examples:

```vdjscript
eq_high 75%
eq_low 0%
eq_kill_high

Kill button pattern for a skin button:

```xml
<button action="eq_kill_high" query="eq_kill_high">
  <off color="#1C1F24" border="#444"/>
  <on  color="#FF4444" border="#FF4444"/>
  <text text="HI KILL" color="white"/>
</button>
```

Sources:

- `Official`: VDJScript verbs appendix
- `Built-in skin`: shipped desktop skins use `eq_high`, `eq_mid`, `eq_low`, `eq_kill_*`, and `eq_mode +1` in knob/label controls
- `Inference`: `eqMode` and equalizer frequency settings in configuration docs provide setting-side context, not direct verb behavior proof

Needs local test:

- `eq_high_freq`, `eq_mid_freq`, `eq_low_freq`: confirm accepted units/ranges and whether they mirror the `equalizer*Frequency` settings exactly.
- `eq_high_slider`, `eq_mid_slider`, `eq_low_slider`: confirm controller-slider value scale in mapper contexts; built-in skin XML uses the non-`_slider` verbs with `frommiddle="true"`.

### `get_browsed_*` — Browsed Track Metadata

These verbs return metadata for the track currently highlighted in the browser,
not for the loaded deck. Use them in `<textzone>` format strings or skin `query=` color expressions
to build an info panel that updates as the user browses.

All are Text-surface verbs (read-only). None take a deck scope — they always reflect the browser selection.

| Verb | Returns | Source |
| --- | --- | --- |
| `get_browsed_title` | Track title | `Official` |
| `get_browsed_artist` | Artist name | `Official` |
| `get_browsed_artist_title` | `Artist - Title` combined | `Official` |
| `get_browsed_title_artist` | `Title - Artist` combined | `Official` |
| `get_browsed_album` | Album name | `Official` |
| `get_browsed_bpm` | BPM as a string | `Official` |
| `get_browsed_key` | Musical key | `Official` |
| `get_browsed_genre` | Genre tag | `Official` |
| `get_browsed_comment` | Comment tag | `Official` |
| `get_browsed_composer` | Composer tag | `Official` |
| `get_browsed_filepath` | Full file path | `Official` |
| `get_browsed_color` | Track color (returns a color value) | `Official` |
| `get_browsed_header` | Column header label for sorting context | `Official` |
| `get_browsed_scrollpos` | Current browser scroll position (numeric) | `Official` |
| `get_browsed_scrollsize` | Total browser scroll range (numeric) | `Official` |
| `get_browsed_selection_index` | Selected row index in the visible browser list | `Official` |
| `get_browsed_folder` | Name of the currently open folder | `Official` |
| `get_browsed_folder_path` | Full path of the currently open folder | `Official` |
| `get_browsed_folder_icon` | Icon identifier for the current folder | `Official` |
| `get_browsed_folder_tab` | Active browser tab | `Official` |
| `get_browsed_folder_scrollpos` | Folder list scroll position | `Official` |
| `get_browsed_folder_scrollsize` | Folder list scroll range | `Official` |
| `get_browsed_folder_selection_index` | Selected row in the folder list | `Official` |

Contrast with deck metadata verbs (loaded track, not browsed):
`get_artist`, `get_title`, `get_bpm`, `get_key`, `get_genre`, `get_comment`.

`get_browsed_selection_index` can be used by custom browser skins that need row-relative selection state. The official appendix describes forms such as `get_browsed_selection_index 1 3` for testing whether row 1 is selected in a three-line browser and `get_browsed_selection_index 3` for returning the selected line number in a three-line browser.

Browser info panel example (skin XML):

```xml
<group x="0" y="0">
  <textzone>
    <pos x="0" y="0"/><size width="400" height="20"/>
    <text fontsize="13" weight="bold" color="white" action="get_browsed_artist_title"/>
  </textzone>
  <textzone>
    <pos x="0" y="22"/><size width="200" height="18"/>
    <text fontsize="11" color="#93A1B1" format="`get_browsed_bpm` BPM  `get_browsed_key`"/>
  </textzone>
  <textzone>
    <pos x="0" y="42"/><size width="400" height="18"/>
    <text fontsize="11" color="#93A1B1" action="get_browsed_genre"/>
  </textzone>
  <visual type="color" source="get_browsed_color">
    <pos x="0" y="60"/><size width="400" height="3"/>
  </visual>
</group>

### Cue Points

#### Core cue verbs

| Canonical | Aliases | Surfaces | Description | Source |
| --- | --- | --- | --- | --- |
| `cue` | — | `Map`, `SkinAction` | Set or jump to the main cue point. Hold to set while stopped; press during play to jump. | `Official` |
| `cue_stop` | — | `Map`, `SkinAction`, `SkinQuery` | Jump to cue and stop. Query: returns `on` when at cue position. | `Official` |
| `cue_play` | — | `Map`, `SkinAction` | Jump to cue and play. Releases to cue position on up if held. | `Official` |
| `cue_button` | — | `Map`, `SkinAction` | Hold-to-preview cue behavior: plays from cue while held, returns on release. | `Official` |
| `cue_cup` | — | `Map`, `SkinAction` | CUP (Cue Up and Play): jump to cue and immediately start playing. | `Official` |
| `cue_3button` | — | `Map`, `SkinAction` | Three-button cue mode (Cue / Play / Stop). | `Official` |
| `cue_select` | — | `Map`, `SkinAction` | Select the active cue point by number. | `Official` |
| `cue_color` | — | `Text`, `SkinQuery` | Returns the color of the specified cue point. | `Official` |
| `cue_name` | — | `Text` | Returns the name of the specified cue point. | `Official` |
| `cue_pos` | — | `Text`, `SkinQuery` | Returns the position of the specified cue point. | `Official` |
| `cue_action` | — | `Map`, `SkinAction` | Perform a cue-specific action (context-dependent). | `Official` |
| `cue_loop` | — | `Map`, `SkinAction` | Set a loop at the cue point. | `Official` |
| `cue_loop_hold` | — | `Map`, `SkinAction` | Hold-triggered cue loop. | `Official` |
| `cue_loop_autosync` | — | `Map`, `SkinAction` | Auto-sync cue loop to beat grid. | `Official` |
| `cue_display` | — | `SkinQuery`, `Text` | Returns display state of the cue panel or cue overlay. | `Official` |
| `cue_countdown` | — | `Text` | Returns countdown to the next cue point. | `Official` |
| `cue_countup` | — | `Text` | Returns time elapsed since the last cue point. | `Official` |
| `cue_counter` | — | `Text` | Returns the total number of cue points set on the loaded track. | `Official` |
| `cues_options` | — | `SkinAction` | Open the cue options menu. | `Official` |
| `goto_cue` | — | `Map`, `SkinAction` | Jump to a cue point by number: `goto_cue 1`, `goto_cue +1` (next). | `Official` |
| `auto_cue` | — | `Map`, `SkinAction` | Toggle auto-cue (jump to first beat on load). | `Official` |

#### Cue point numbering

Cue points are numbered from `1`. Most verbs accept a literal slot number or `+1`/`-1` to step through them.

#### `cue_pos` and position format

`cue_pos` returns position in the unit determined by the current `display_time` setting.
When used in a `query=""` or condition, it returns `on` if that cue slot is set, `off` if empty.

```vdjscript
cue_pos 1
cue_pos 1 ? on : off
```

#### Pad page pattern: 8 hot cues with color

```xml
<pad1 name="`cue_name 1`" color="cue_pos 1 ? cue_color 1 : dim"
      query="cue_pos 1 ? on : off">
  cue_pos 1 ? goto_cue 1 : cue_select 1 &amp; cue
</pad1>
```

Breakdown:
- `color=` uses `cue_color 1` when the cue is set, falls back to `dim`
- `query=` lights the pad only when the cue is set
- action: if set, jump to it; if not, select slot 1 and set a cue there

Use `param_cast 'beats'` when a computed BPM should be passed to `pitch` as a target BPM:

```vdjscript
param_multiply 1.333333 get_bpm & param_cast 'beats' & deck 2 pitch
```

| `is_using`                  | Query whether a feature was recently used | `is_using 'filter' 1000ms`   |

### Skin Context Notes

- `is_using` is built for temporary context panels and stacked feedback. Official feature names include `filter`, `equalizer`, `loop`, `cue`, `sample`, `pads`, `effect`, and `load`. `Local test` (2026-09-02, arg-form probe): nine of those separate from nonsense as the first token — `cue`, `effect`, `equalizer`, `filter`, `load`, `loop`, `loopsize`, `sample`, `stems` — and `loop` correctly reads `yes` only in the `loop_active` fixture. A bare `is_using` returns `E_INVALIDARG`, so the feature name is required. `inaudible` alone errors and is not a feature name; whether it works as a second token modifier is **unresolved** — `is_using effect inaudible` read `yes` with an effect active in one run and `no` in another, so the artifact marks the verb disputed.
- Optional timing parameters keep the state true long enough for UI feedback, for example `is_using 'sample' 1000ms 8000ms`.

### System Notes

- `debug` is mainly useful while developing mappings because it displays the parameter value a controller or script path is sending.
- `handshake` is for plugin developers. Pass a string, then verify the encrypted response using VirtualDJ's public key before trusting that the caller is a real VirtualDJ environment.
- `system` is official but remains sparse. Local test on VirtualDJ `v2026-m b9336`: in the sparse-helper pad page, `` `system` `` returned blank text and pressing `system` produced no visible UI change or new Log Report entry. Keep it as a conservative catalog entry unless an official example or harmless parameter is found.
- Do not infer `system` semantics from unrelated helpers such as `system_volume`, `has_system_volume`, or system-labeled meter values.

## Variables

| Verb             | Description                   | Example                                     |
| ---------------- | ----------------------------- | ------------------------------------------- |

| `var_not_equal`  | Check inequality              | `var_not_equal "my_var" 42`                 |
| `var_smaller`    | Check less than               | `var_smaller "my_var" 42`                   |
| `var_greater`    | Check greater than            | `var_greater "my_var" 42`                   |
| `set_var_dialog` | Dialog to set var             | `set_var_dialog 'varname'`                  |
| `set`            | Set variable value            | `set 'varname' 5`                           |

| `controllervar`  | Controller-unique variable    | `controllervar`                             |

### Skin Variables and Reloading

Working skins commonly use custom variable names like `@$layout_4deck`, `@$skin_mode`, or `@$show_zoom_racks` for skin-local layout state:

```vdjscript
toggle '@$show_zoom_racks'
set '@$layout_4deck' 1
var_equal '@$layout_4deck' 1 ? action1 : action2
```

If a variable only drives live `visibility=""`, a reload is usually unnecessary. If it drives structural XML such as conditional `<nbdecks>`, conditional `<breaklines>`, mutually exclusive layout branches, or conditional define/color variants, pair the state change with `load_skin` so VirtualDJ reparses the skin:

```vdjscript
set '@$layout_4deck' 1 & load_skin
```

## Window Control

| Verb          | Description                  | Example                 |
| ------------- | ---------------------------- | ----------------------- |
| `close`       | Close application            | `close`                 |
| `minimize`    | Minimize to taskbar          | `minimize`              |
| `maximize`    | Maximize/fullscreen/windowed | `maximize 'fullscreen'` |
| `show_window` | Show/hide window             | `show_window`           |
| `open_stem_creator` | Open the Stem Creator workflow | `open_stem_creator` |

Window/workflow note:

- `open_stem_creator` opens VirtualDJ's Stem Creator dialog. Local test on VirtualDJ `v2026-m b9336`: pressing it from the sparse-helper pad page opened a dialog with Bass, Kick (Drums), HiHat (Optional), Vocals (Optional), Instruments, Instru2 (Optional), Output, Headroom, and Create controls.
- A selected browser track was not auto-filled into that dialog during the local test, and filtering the browser to 0 files opened the same blank dialog. Treat `open_stem_creator` as a workflow opener, not selected-track automation; full stem-file creation/export and license/build gating still need separate testing.

| `beatjump_pad`       | Execute jump            | `beatjump_pad`             |

### Deck Management Notes

- `mixermode` returns true for internal mixer mode and false for external mixer mode; pass `internal` or `external` to test explicitly.
- `beat_juggle` alternates direction each time it runs. Pass a beat amount such as `0.5` for half-beat juggling.
- `dualdeckmode_decks` is official but sparsely documented; official prose ties it to dual-deck mode applying to deck pairs 1/3 or 2/4, so test controller mappings that depend on it.
- Local pad-page result on VirtualDJ `v2026-m b9336`: in [Reference - Dual Deck Mode Test.xml](../tests/Pads/Reference%20-%20Dual%20Deck%20Mode%20Test.xml), current and deck-scoped `dualdeckmode_decks` readbacks stayed false/red after `dualdeckmode` toggled on/blue, and the same behavior was reported from deck 2. Test any visible dual-deck pair/controller context before relying on it.

Local test on VirtualDJ `v2026-m b9336`: in [Reference - Deck Error Test.xml](../tests/Pads/Reference%20-%20Deck%20Error%20Test.xml), it stayed off for normal load/unload states, turned on/red after a deliberately missing file load, scoped to deck 1 while deck 2 stayed off, and cleared after a later successful selected-track load.

### Cue Point Notes

- `cue_pos <n>` returns the position of cue point `<n>` as a percentage of the track, which makes it especially useful anywhere a skin element expects a progress-style value.
- `cue_pos` also supports alternate outputs such as `msec`, `sec`, `min`, `mseconly`, and `beats`.
- In skin XML, pair `cue_pos` with `has_cue <n>` when you want a marker or fill to appear only after that cue exists.
- `shift_all_cues <offset>` is a repair tool for tracks whose cue points are globally early or late, such as old imports that need `shift_all_cues -10ms`.
- `sort_cues` rewrites cue ordering chronologically; avoid putting it on an accidental one-tap control.

### Working `cue_pos` Examples

Basic queries:

```text
cue_pos 1
cue_pos 1 beats
cue_pos 1 mseconly
```

Custom progress bar up to Hot Cue 1:

```xml
<group name="cue_1_progress">
  <square color="#11161D">
    <pos x="40" y="200"/>
    <size width="300" height="6"/>
  </square>

  <visual source="cue_pos 1" type="linear" orientation="horizontal" visibility="has_cue 1">
    <pos x="40" y="200"/>
    <size width="300" height="6"/>
    <off shape="square" color="transparent"/>
    <on shape="square" color="`cue_color 1`"/>
  </visual>
</group>
```

This draws a thin bar from the start of the track up to Hot Cue 1. It is a simple way to turn `cue_pos` into a custom progress overlay above or below a `songpos` bar.

Read-only cue marker driven by a slider:

```xml
<slider action="cue_pos 1" orientation="horizontal" visibility="has_cue 1">
  <pos x="40" y="192"/>
  <size width="300" height="18"/>
  <fader>
    <size width="3" height="18"/>
    <off shape="square" color="`cue_color 1`"/>
  </fader>
</slider>
```

Here the slider range becomes a simple placement track, and the `fader` sits at the cue location. This works well as a thin overlay on top of a `songpos` bar when you want a marker instead of a fill.

## Deck Selection

| Verb              | Description                | Example              |
| ----------------- | -------------------------- | -------------------- |
| `select`          | Select working deck        | `select`             |
| `masterdeck`      | Select/unselect master     | `masterdeck`         |
| `masterdeck_auto` | Auto masterdeck            | `masterdeck_auto`    |
| `leftdeck`        | Select left deck           | `leftdeck +1`        |
| `rightdeck`       | Select right deck          | `rightdeck +1`       |
| `invert_deck`     | Swap left/right deck       | `invert_deck`        |
| `leftcross`       | Assign to left crossfader  | `leftcross`          |
| `rightcross`      | Assign to right crossfader | `rightcross`         |
| `cross_assign`    | Assign deck to crossfader side or through state | `deck 3 cross_assign 'left'` |
| `pfl`             | Send to headphones         | `pfl`, `pfl 75%`     |
| `get_deck_color`  | Get deck color             | `get_deck_color 50%` |

### Crossfader Assignment Notes

- `leftcross` and `rightcross` assign a deck to the left or right side of the audio crossfader.
- `cross_assign` is the more explicit side selector and supports values such as `left`, `right`, and `thru`.
- Use deck scoping when assigning a specific deck: `deck 3 cross_assign 'left'`.

`filter_selectcolorfx`: pops up a gui selector for colorfx effects

### Stem Names

- Individual: `Vocal`, `HiHat`, `Bass`, `Instru`, `Kick`
- Aggregate: `Melody` (Instru+Bass), `Rhythm` (HiHat+Kick), `MeloRhythm`, `Acapella`, `Instrumental`

### Stem Isolation Notes

- **Official**: `only_stem <stem>` isolates the named stem. `mute_stem <stem>` mutes the named stem.
- **Local test**: for common vocal/instrumental isolation, prefer the aggregate stem-pad states: `stem_pad 'acapella' on` and `stem_pad 'instrumental' on`. These force the selected aggregate state on in isolation, so they are cleaner than `only_stem <stem> on/off` for those two cases.
- **Local test**: `only_stem <stem> on` and `only_stem <stem> off` are accepted, but they are state-dependent rather than simple absolute setters.
- `only_stem 'vocal' on`: if vocal is already on, this turns the non-vocal stems off. If vocal is off, the first press turns vocal on and leaves the other stems untouched; a second press then isolates vocal.
- `only_stem 'vocal' off`: mirror behavior for the non-vocal side. If vocal is already off, this turns the non-vocal stems on. If vocal is on, the first press turns vocal off and leaves the other stems untouched; a second press then isolates the non-vocal stems.
- For arbitrary deterministic combinations beyond the aggregate stem-pad states, use `mute_stem <stem> on/off` and explicitly set the stems you want muted or unmuted.

### EQ Crossfader Notes

- `eq_crossfader_high`, `eq_crossfader_mid` / `eq_crossfader_med`, and `eq_crossfader_low` crossfade EQ bands between decks instead of changing one deck's EQ amount.
- Use the label helpers when a skin should display the active EQ mode's band names instead of hard-coded `HIGH`, `MID`, and `LOW`.

```text
eq_crossfader_high 50%
eq_crossfader_mid 50%
eq_crossfader_low 50%
`high_label`
```

### Key, Pitch And Motor Notes

- `key_match_button` matches the other deck's key on first press, then resets the key on second press.
- `key_match_menu` is the popup/menu partner and is a natural `rightclick=""` action for key displays.
- `pitch <number>` treats the value as pitch-slider position within the current `pitch_range`; `pitch <percent>` sets absolute playback speed, so `pitch 112%` means +12%.
- `pitch <beats>` sets pitch to match a target BPM-style value, for example `pitch 128bt`.
- For calculated tempo relationships, compute the target with parameter math, cast it to `beats`, then feed it to the destination deck's `pitch`.
- `pitch_relative` is for hardware controls that should move relative to the software pitch position instead of replacing it with an absolute hardware value.
- `pitch_lock` links matched deck pitch sliders so moving one keeps the match by moving the other.
- `startupspeed` and `brakespeed` control vinyl-style ramp behavior; larger values mean longer ramp times.
- `backspin` accepts explicit durations such as `5000ms` or beat lengths such as `4bt`.

```text
pitch 128bt
param_multiply 1.333333 get_bpm & param_cast 'beats' & deck 2 pitch
pitch_relative +0.1%

### Loop Behavior Notes

- `repeat_song` restarts the whole loaded track at the end. It is separate from active loop state and saved-loop slots.

### Saved Loop Notes

- `loop_load <n>` jumps to and activates an existing saved loop.
- `loop_load_prepare <n>` activates/deactivates the saved loop without jumping to its start point.
- `saved_loop <n>` loads an existing saved loop, or stores the current loop in that slot if it does not exist.
- `saved_loop_prepare <n>` is the prepare-style equivalent: activate/deactivate an existing saved loop without jumping, or set it if missing.
- `saved_loop_display <n>` follows the `savedLoopDisplay` option and is suitable for pad labels. Use `saved_loop_display +1` or named menu entries to change the display mode.
- `loop_color <n>` can query or set the color of a saved loop, making it the right color source for saved-loop pads.
- `saved_loop_autotrigger <n>` toggles whether the saved loop should trigger automatically when playback reaches it.

### Saved Loop Examples

```text
loop_load 1
loop_load_prepare 1
saved_loop_prepare 1
saved_loop_autotrigger 1
saved_loop_display 'length'
loop_color 1 'yellow'
```

```xml
<pad1 name="`saved_loop_display 1`" color="loop_color 1"
      query="loop_load 1 ? loop_load_prepare 1 ? blink : on : off">
  holding ? loop_delete 1 : loop_load 1 ? loop_load_prepare 1 : loop_save 1
</pad1>
```

### Generic Pad Notes

- Pad pages are generic VDJScript surfaces. The selected page may contain hot cues, FX, loops, sampler actions, custom buttons, or controller-specific actions.
- Use `pad_has_action <n>` when a skin/controller needs to know whether the current page defines a push action for pad `<n>`.
- Use page-specific queries when documenting a page's own behavior: for example `has_cue <n>` for cue occupancy, `effect_active` / `effect_has_*` for FX state, and `sampler_loaded <absolute-slot>` only for sampler-slot occupancy.
- Do not use `sampler_loaded` as a generic test for whether the current pad page defines an action.

### Pad FX Notes

- Official `padfx` behavior is temporary: parameters are applied when the pad effect starts and return when it stops.
- Use `padfx` for volatile pad-owned performance effects that should not overwrite the performer's persistent FX1-FX6 rack.
- The direct `padfx 'effect' <param...> 'stemfx:<stem>'` syntax is specific to Pad FX. Persistent slot FX use separate `effect_select`, `effect_slider`, `effect_button`, and `effect_active` commands instead of a single inline-parameter selector.
- After slider values, `padfx` can also accept switch strings such as `"TRAIL:on"` and stem modifiers such as `stemfx:<stem>`, `solostem:<stem>`, or `mutestem:<stem>`.
- Use `stemfx:<stem>` when the effect should apply only to that stem while other stems continue playing normally.
- Official `padfx` stem names are `Vocal`, `HiHat`, `Bass`, `Instru`, `Kick`, `Melody`, `Rhythm`, `MeloVocal`, and `MeloRhythm`; local pad pages normally use lowercase strings.
- Stem echo-out forum examples often use a fuller argument list rather than only strength and beat length; keep effect-specific parameter order close to the source example or local test.
- `padfx` does not provide a documented per-pad ownership namespace. User-provided testing indicates that another pad using the same effect and stem target can alter the active pad-FX parameters for that shared identity.
- Use `effect_disable_all 'padfx'` only as a separate broad cleanup/reset action, and only when clearing other temporary Pad FX is acceptable. User-provided testing found that chaining it immediately before new `padfx` calls in the same pad can prevent those new pad FX from activating or lighting.

```vdjscript
padfx 'echo out' 80% 'solostem:vocal'
padfx 'echo out' 'mutestem:rhythm'
padfx 'reverb' 'stemfx:vocal'
padfx 'echo out' 85% 70% 62.5% 20% 'stemfx:vocal'
padfx 'echo out' 80% 1bt 25% 75% 'stemfx:vocal'
effect_show_gui 'vocals' 'echo' & padfx 'echo' 'stemfx:vocal'
```

Safer cleanup shape:

```vdjscript
# Separate reset/cleanup pad
effect_disable_all 'padfx'

# Performance pad: start the requested Pad FX directly
padfx 'echo out' 80% 1bt 'stemfx:vocal' & padfx 'reverb' 75% 'stemfx:vocal'
```

FX catalog note:

- `get_mixfx_active` appears in the official appendix and has sparse official prose. Local pad-page test on VirtualDJ `v2026-m b9336`: after loading a track, `` `get_mixfx_active` `` returned `off`/`on` and its query state mirrored `effect_mixfx_activate` while switching the selected Mix FX between Filter and Echo.
- Numbered deck FX slots 1-6 are the supported range to use in reference examples. The manual exposes an `FX x6` deck view, hardware manuals describe six VirtualDJ FX slots, and `effect_bank_save` / `effect_bank_load` explicitly save/load deck FX slots 1-6. User-provided local observation on 2026-06-01 found that FX1-FX6 kept their loaded effect across a VirtualDJ restart, while FX7 and higher plus named stem FX slots kept their loaded effect only during the current session/across track loads and reset after restart.
- Treat FX1-FX6 as persistent rack state. Pads that should use the performer's saved rack should usually trigger or adjust existing slots; pads that select effects into FX1-FX6 are intentionally reprogramming the rack.
- Treat `padfx` and named stem FX slots as volatile, stateful performance targets. They are appropriate when pads should assign their own effect state without becoming the saved deck rack.
- There is no known one-command persistent-slot equivalent to `padfx 'cut' 90% 0.5bt 50% 'stemfx:vocal'`; use `effect_select` plus explicit `effect_slider`/`effect_button`/`effect_active` steps when a pad intentionally writes FX1-FX6.
- `effect_bank_save` / `effect_bank_load` are official rack snapshot helpers for deck FX slots 1-6. Treat them as persistent rack helpers. If a pad uses explicit `effect_select` / `effect_slider` / `effect_active` macros to guarantee preset values in FX1-FX6, document that it intentionally reprograms the rack.
- `effect_disable_all 'padfx'` clears temporary Pad FX, but should be documented as a broad cleanup/reset control rather than an inline initializer before new `padfx` actions.
- `effect_3slots_layout` is a UI/layout helper; built-in and SDK example skins use it to switch between single-FX and multi-FX panels.
- `effect_select_popup` opens the native selector and is appropriate for right-clicks, parameter buttons, or skin affordances. It is not a read-only selected-name query.
- `effect_select_toggle` is documented as keeping activation continuity while selecting an effect; use it only when that continuity is deliberate. Use plain `effect_select` for replacement and `effect_select_multi` for multi-effect-per-slot behavior.
- Generic FX panels should use introspection helpers instead of hardcoded parameter maps: `effect_has_slider`, `get_effect_slider_label`, `get_effect_slider_text`, `effect_has_button`, and `get_effect_button_shortname`. Built-in skins use these helpers for deck FX, video FX, and transition controls. `Local test` (VirtualDJ `v2026-m b9482`, deck FX slot 1, Backspin): `get_effect_name`, `get_effect_slider_count`/`get_effect_button_count`, `effect_has_slider`/`effect_has_button`, and `get_effect_slider_text` are reliable and match the GUI. `get_effect_slider_label_full`/`get_effect_slider_name` return the full label (`Strength`), while `get_effect_slider_label`/`get_effect_slider_shortname` return the short form (`STR`). `get_effect_slider_default` takes a target (slot number, effect name, or `'active'`), optional index, and a trailing fallback, returning a normalized 0-1 default: `'<effect>' <fallback>` reads it as text; `<slot> <index> <fallback>` is the value-context form skins use in `<slider frommiddle=>`. See the helper reliability table in [Effects Engines](Effects%20Engines.md#effect-introspection-and-dynamic-controls).
- `effect_releaseslider` / `effect_releaseslider_active` are release-FX-specific slider paths; keep them separate from normal slot `effect_slider` examples until a local release-FX fixture records selection and query behavior.
- `effect_fxsendreturndeck`, `effect_fxsendreturndeck_multi`, and `effect_fxsendreturnenable` are send/return routing helpers. Their practical behavior depends on mixer/routing context, so they should be documented as workflow-specific, not default deck-FX controls.
- `effect_command` is plugin-specific. Built-in BeatGrid plugin UI XML uses commands such as `set 00`, `get 00`, and `cur 0`; do not generalize those strings to other plugins without plugin UI evidence or a local test.

Common dynamic-control pattern:

```xml
<slider action="effect_slider 1 1"
        dblclick="effect_slider_reset 1 1"
        disabled="not effect_has_slider 1 1"
        frommiddle="get_effect_slider_default 1 1 0.5"/>
<text action="get_effect_slider_label 1 1"/>
<button action="effect_button 1"
        visibility="effect_has_button 1"
        textaction="get_effect_button_shortname 1"/>
```

Video FX note:

- Built-in desktop skins model video FX like a parallel slot family: `video_fx_select` chooses the plugin, `video_fx` toggles it, `video_fx_slider` moves parameters, `video_fx_button` presses plugin buttons, and `get_videofx_name` / `get_video_fx_slider_label` drive text. Use `deck master video_fx...` when targeting master video effects.
- Video transitions are a separate path: `video_transition_select` chooses the transition, `video_transition` runs it, and `video_transition_slider` / `video_transition_button` address transition controls.

### Sampler Modes

- `on/off` - One press starts the sample, the next press stops it, or it stops when it reaches the end.
- `hold` - The sample plays only while the pad is held.
- `stutter` - Each press restarts the sample from the beginning.
- `unmute` - The sample keeps running, but is only audible while the pad is held.

### Sampler Notes

- `sampler_pad_page` is the pager behind Parameter 2 on the default Sampler pad page and is the main way to reach `9-16`, `17-24`, and later sub-pages in banks with more than 8 samples.
- In tested pad/skin contexts, `sampler_pad_page` returns display ranges such as `"1 to 8"` and `"9 to 16"`, not simple numeric page indexes.
- For drag-and-drop assignment on custom pad pages, use pad `drop="sampler_assign <absolute-slot>"`.
- Treat `sampler_assign` as an absolute-slot helper unless you have verified a build-specific page-aware variant; the current official docs do not show an `"auto"` form for it.
- `sampler_pad`, `sampler_color`, and `sampler_pad_volume` are the safest page-aware helpers when building sampler pad pages.
- In display contexts such as pad `name=` fields and skin/text `format=` fields, `sampler_pad 1` through `sampler_pad 8` are the safest way to show the current visible sample names on the active sampler page.
- For visibility and empty-slot checks in paged sampler UIs, use `sampler_loaded` with the absolute slot behind the visible pad. Example: page 2 pad 8 should be guarded by `sampler_loaded 16`, not `sampler_loaded 8` or `sampler_loaded 8 "auto"`.
- For 16-pad pad pages, pads `9-16` are the next eight visible sampler positions. Example: on page `"9 to 16"`, pad 16 is backed by absolute slot 24.
- To nullify an empty sampler pad, use an explicit false branch in each relevant field: blank text in `name`, dim/off visual state in `color`/`query`, and `: nothing` in the action body.
- For intentionally blank sampler pad labels, prefer `get_text ' '` rather than an empty string; local testing showed empty strings can fall back to visible slot numbers on later sampler pages.
- For a confirmed read-only implementation, see [SAMPLER READ ONLY.xml](../examples/Pads/Quarantine/SAMPLER%20READ%20ONLY.xml).
- When defining `shift_pad<n>` entries for sampler pages, also define shifted `color=""` values such as `sampler_loaded 1 ? sampler_color 1 : dim`; skin pad frameworks may render shifted pad colors separately, and missing shifted colors can fall back to the skin/default button color. Source: `Local test`, `Inference`
- `sampler_play`, `sampler_stop`, `sampler_volume`, `get_sample_name`, `get_sample_info`, and `get_sample_color` are best treated as absolute-slot helpers.
- `sampler_default` is the official alias of `sampler_select`; prefer `sampler_select` in new docs unless documenting older mappings.
- `sampler_rapidfire` is the official alias of `sampler_mode`; prefer `sampler_mode` for clarity.
- Use `sampler_color` when you want the color of the currently visible sampler pad. Use `get_sample_color` when you want the actual stored color of a specific bank slot.
- In skins, do not assume a normal `<button>` exposes a drag callback that mirrors pad `drop=`. The current skin docs describe click handlers on `<button>` and separate `<dropzone>` elements for drag targets.
- Samples triggered from a deck sync to that deck. If you want a pad page to follow a predictable sync source, trigger through an explicit deck:

```text
deck active sampler_pad 1 "auto"
deck master sampler_pad 1 "auto"
```

- `deck master` means the current master deck context, not a separate global sampler namespace.
- In skin XML, raw `deck master sampler_pad <n>` can be less reliable than an explicit deck number in some sampler title/query paths. If a paged sampler title shows the wrong slot, resolve the master deck explicitly:

```text
deck 1 masterdeck ? deck 1 sampler_pad 1 : deck 2 masterdeck ? deck 2 sampler_pad 1 : deck 3 masterdeck ? deck 3 sampler_pad 1 : deck 4 masterdeck ? deck 4 sampler_pad 1 : sampler_pad 1
```

- If you want the traditional left-deck `1-8` and right-deck `9-16` behavior, either page the second deck manually with `sampler_pad_page +1` or enable the `samplerSpanAcrossDecks` option.

### Sampler Group Notes

- Sampler group helpers accept a group name or group index where the official appendix says either form is valid.
- Use `sampler_group_mute` when the UI should mute a logical group instead of a single sample slot.
- Use `sampler_volume_nogroup` when one sample must change without also changing other samples in the same group.
- `sampler_has_group` is useful before showing group controls for banks that may not define that group.
- `sampler_load_to_deck` loads the selected sampler slot to a deck; for scratchbank-style workflows, prefer the dedicated `scratchbank_load_to_deck`.

### Working Sampler Examples

```text
sampler_pad 1
sampler_loaded 1 ? sampler_pad 1 : sampler_rec 1
sampler_pad_page +1
sampler_bank +1
sampler_options "locked"
sampler_pad_volume 1 75%
sampler_volume 9 75%
sampler_has_group "horns" ? sampler_group_mute "horns" : nothing
sampler_group_volume "horns" 75%
sampler_load_to_deck
```

```xml
<pad1 drop="sampler_assign 1">...</pad1>
```

## Sync

| Verb           | Description                 | Example          |
| -------------- | --------------------------- | ---------------- |
| `sync`         | Synchronize with other deck | `sync`           |
| `match_bpm`    | Match BPM only              | `match_bpm`      |
| `is_sync`      | Query synchronized BPM/phase state | `is_sync` |
| `match_gain`   | Match gain to the other deck | `match_gain` |
| `play_sync`    | Play synchronized           | `play_sync`      |
| `play_onbeat`  | Play synchronized to local beat | `play_onbeat` |
| `beatlock`     | Keep synchronized           | `beatlock`       |
| `smart_fader`  | Sync while crossfading      | `smart_fader`    |
| `phrase_sync`  | Match phrase                | `phrase_sync 16` |
| `quantize_all` | Set all quantize options    | `quantize_all`   |
| `auto_bpm_transition` | Gradually move BPM toward the other deck; an optional parameter forces which BPM it lands on | `auto_bpm_transition 'target_current'` |
| `auto_bpm_transition_options` | Enable/disable features of the transition; first parameter names the feature | `auto_bpm_transition_options 'stems' 'vocal'` |
| `get_bpm_match` | Return BPM match amount | `get_bpm_match` |
| `sync_hint` | Query sync hint such as pitch or phase | `sync_hint "phase"` |
| `bpm_stabilizer` | Lock fluid track to current BPM | `bpm_stabilizer` |

Important notes:

- `auto_bpm_transition` gradually moves this song's BPM to the other deck's while keeping both
  playing at the same BPM; with `smartPlay` or `autoBPMMatch` on it moves at normal speed. The
  optional parameter **forces which BPM the transition targets**: `'source_original'`,
  `'target_original'` or `'target_current'` (`Official`, VDJScript verbs appendix).
- `auto_bpm_transition_options` takes the feature as its first parameter — `'length'`, `'loop'`,
  `'stems'`, `'master_tempo'` or `'autostart'` — and features that need a value take a **second
  token**: the appendix's own example is `auto_bpm_transition_options 'stems' 'vocal'` to
  disable a specific stem. This is documented confirmation of the two-token tail that
  [tests/verb-arg-forms.json](../tests/verb-arg-forms.json) found structurally.
- **Do not read the 2026-09-03 execute-probe result as evidence against these parameters.**
  That probe's observable was the verb's own boolean readback, which reports whether a
  transition is *running*; the parameters steer which BPM it lands on, which that observable
  cannot see. The three parameter tokens looked identical to junk for that reason alone. A
  valid test needs two decks at different BPMs and a readback of the resulting BPM over time.

## Video

| Verb               | Description             | Example                   |

| `video_output`     | Select monitor          | `video_output 1`          |
| `video_crossfader` | Video crossfader        | `video_crossfader`        |
| `video_crossfader_link` | Link video crossfader to audio crossfader | `video_crossfader_link on` |
| `video_crossfader_auto` | Automatically move video crossfader based on deck activity | `video_crossfader_auto on` |
| `video_fadetoblack` | Fade video to black from volume sliders | `video_fadetoblack on` |
| `video_delay`      | Offset video/audio sync delay | `video_delay +100ms`     |

| `video_transition` | Launch transition       | `video_transition 1000ms` |
| `is_video`         | Check if has video      | `is_video`                |
| `is_audioonlyvisualisation` | Check whether audio-only visualisation is running | `is_audioonlyvisualisation` |
| `over_video` / `overvideo` | Force this deck's video output to video master | `over_video on` |

### Video Notes

- `leftvideo` and `rightvideo` assign decks to the video crossfader sides; the `_button` variants are simple source-button helpers for skins or mappings.
- `video_crossfader_link` ties the video crossfader to the audio crossfader. Use `video_crossfader_auto` when VirtualDJ should move the video crossfader based on which side is playing, cueing, or scratching.
- `video_delay` accepts millisecond-style relative and reset values such as `+100ms`, `-100ms`, and `0ms`.
- `video_level` is separate from the main video crossfader and is used for fade-to-black style level control.
- `over_video` is forceful: it puts this deck's video output on the video master regardless of normal assignment logic.

### Video Examples

```text
deck 3 leftvideo
deck 4 rightvideo
video_crossfader_link on
video_crossfader_auto on
video_delay 0ms
is_video ? video_transition 1000ms : nothing
```

### Controller Notes

- `assign_controller` assigns a physical controller to a deck. In a controller mapping, `deck 1 assign_controller` assigns the controller that sent the action.
- `controller_mapping` changes the mapping used by a controller. With one argument it targets the controller that ran the action; with controller name and optional instance number it can target a specific device family or unit.
- `mixer_order` is for 4-deck controller layouts; `mixer_order 3124` means the mixer strips appear left-to-right as decks 3, 1, 2, 4.
- `menu_button <n> "page,page,page"` defines controller buttons whose behavior can be changed by `menu`. Use `browser_scroll` to navigate the controller-screen menu.
- `show_text 'Line 1|Line 2' 3000ms` sends temporary text to controller displays that use `get_display`; `|` separates display lines.
- `reinit_controller` can target a specific controller and optional delay between exit/init. Use broad `reinit_controller` only when a full controller reinitialization is intended.
- `midiclock_active`, `miditovst_active`, `phase_*`, `rzx_*`, `v7_status`, `djc_*`, `controllerscreen_deck`, and `controller_battery` are official but hardware-specific or sparsely documented; keep them in mappings that can be tested on the target device.
- Use [VDJScript Local Test Tracker](VDJScript%20Local%20Test%20Tracker.md) for build/hardware results before promoting `controllerscreen_deck`, `controller_battery`, `gemini_waveform_zoomlevel`, `phase_*`, `v7_status`, `rzx_*`, `djc_*`, or `denon_platter` beyond compact controller notes.

### Controller Examples

```text
deck 1 assign_controller "CDJ400" 2
controller_mapping "CDJ400" "My Mapping" 2
mixer_order 3124
menu_button 1 "hotcue,sampler,effect,loop"
show_text 'Line 1|Line 2' 3000ms
reinit_controller "My Controller" 200ms
```

OS2L source note:

- The official DMX pad page uses `os2l_button` for named lighting buttons, `os2l_cmd <n> on while_pressed` for numbered commands, and `os2l_info` in the page menu.
- `os2l_scene` is similar to `os2l_button`, but the scene is only sent when the deck is audible; when the deck is not audible, it queues until the deck becomes audible.

### Configuration Notes

- `setting_setsession` and `setting_setsession_deck` force temporary values for the current VirtualDJ session without treating them as ordinary persisted preferences.
- `setting_setdefault` and `setting_reset` are stronger controls than ordinary `setting`; avoid putting them on casual one-tap skin buttons unless the UI makes that intent clear.
- `auto_pitch_lock` ties into matched-BPM workflows: when enabled, pitch lock engages when BPMs are matched so moving one pitch slider moves the other to keep the match.
- `play_mode` controls play/stop/cue behavior families such as `numark` and `pioneer`.
- `saveregistryconfig` is the official alias of `save_config`.
- `connect` works as both an account/connect action and a login-state query. Local test on VirtualDJ `v2026-m b9336`: logged in returns on/green and opens a small menu with `Log out`; logged out returns off/red and opens the CONNECT login dialog.
- Official skins use `connect` as an account/connect button; keep skin usage account-state aware so logged-in and logged-out users get sensible behavior.

## Timecode

| Verb              | Description             | Example                 |
| ----------------- | ----------------------- | ----------------------- |
| `timecode_active` | Enable timecode control | `timecode_active 1 on`  |
| `invert_timecode` | Switch/invert timecode control across available decks | `invert_timecode` |
| `timecode_mode`   | Set mode                | `timecode_mode 'smart'` |
| `timecode_config` | Open timecode configuration | `timecode_config` |
| `timecode_bypass` | Use as line input       | `timecode_bypass`       |
| `timecode_reset_pitch` | Reset software pitch so deck pitch matches turntable pitch | `timecode_reset_pitch` |
| `timecode_pitch`  | Tell timecode engine a controller pitch-slider position | `timecode_pitch 100%` |
| `timecode_cd_mode` | Force timecode to CD mode | `timecode_cd_mode on` |
| `timecode_motor_enable` | Hybrid turntable motor-state helper | `timecode_motor_enable on` |
| `timecode_options` | Show timecode options  | `timecode_options`      |
| `get_hastimecode` | Check if has timecode   | `get_hastimecode`       |
| `get_timecode_quality` | Timecode signal quality | `get_timecode_quality` |

### Timecode Notes

- `timecode_active <source> on` can assign the same timecode source to multiple decks, for example `deck 1 timecode_active 1 on & deck 2 timecode_active 1 on`.
- `timecode_mode` accepts the official modes `smart`, `absolute`, and `relative`.
- Use `timecode_reset_pitch` when you need software pitch to match the turntable pitch exactly before absolute needle-drop work.
- `timecode_pitch` is for controllers that send pitch separately over MIDI while timecode controls position.
- `timecode_cd_mode` is for CD or digital devices using a vinyl-style timecode signal.
- **It latches for the session.** `Local test` (2026-09-03): executing `timecode_cd_mode on`
  sets it to `yes` on all four decks, and it cannot be cleared from script — `off`, `0`, the
  bare toggle and deck-scoped forms all leave it `yes`. Restarting VirtualDJ restores `no`, and
  the value is absent from `settings.xml`, so this is runtime-only state that script can set but
  not unset. Treat it as one-way within a session.

### Timecode Examples

```text
deck 1 timecode_active 1 on
timecode_mode 'relative'
timecode_reset_pitch
timecode_pitch 100%
get_hastimecode ? timecode_options : timecode_config
```

## Common Patterns

### Conditional Execution

```
condition ? action_if_true : action_if_false
```

### Backtick Queries

Use backticks to execute queries within actions:

```
set 'varname' `play`
param_equal `get_browsed_song 'type'` "audio"
```

### Time Units

- `ms` - milliseconds
- `bt` - beats
- `%` - percentage

### Deck Specification

Prefix action with deck number:

```
deck 1 play
deck 2 volume 50%
deck master get_level
```
