Dice Roll
0 rolled off
Tick the lanes to roll, then press Roll. Probability notes (< 100%) may be rolled off and appear faded. Tap a faded cell to bring it back manually. Finalise removes faded cells permanently.
Dynamics (velocity ramp)
Linearly ramp velocity across existing notes in a lane. For quick taps, long-press a cell and use "Ramp from here…" — this card is for precise control.

Export
Different drum VSTs use slightly different MIDI note numbers. Pick General MIDI for most cases, or build a custom profile for your specific VST (Superior Drummer, EZDrummer, GGD etc.) and notes will be remapped on export.
Email the .mid to yourself or drop in a synced folder
(iCloud, Drive, Dropbox) for your DAW to pick up.

Backup & restore
Backup downloads a single JSON file with every section, all user-saved grooves, your mixer levels, and all settings. Restore lets you reload that file later (overwrites everything currently in the app).
