VirtualGrandMA is a lightweight Windows application that simplifies the creation and management of virtual USB drives for MA Lighting’s GrandMA onPC software (and others!)
It provides a modern, intuitive UI and handles everything from .img creation to automatic mounting using the ImDisk Toolkit — no command-line work needed.
✅ Create Virtual USB Images
Quickly create new .img or .vhd files in any size (GB). Perfect for simulating USB drives for GrandMA show files.
✅ Mount & Unmount Instantly
Mount your image as a removable USB drive with one click using ImDisk. Unmount cleanly when done.
✅ Automatic FAT32 Preparation
Every mounted image is ready for GrandMA — ideal for fixture libraries, show backups, or exports.
✅ Recent Images List
The 10 most recently used .img files are automatically tracked and displayed for fast access.
✅ ImDisk Installer Integration
If ImDisk Toolkit isn’t found, VirtualGrandMA will prompt and install it automatically using the included install.bat and files.cab.
✅ Integrated Console View
Optional console output for debugging or monitoring backend operations.
The console can be shown or hidden dynamically — closing it won’t quit the main app.
✅ Modern UI
Built with the ReaLTaiizor framework for a clean, dark, and modern Windows Forms experience.
