APC Mini MK2 MIDI Protocol Reference
Quick reference for MIDI protocol. For complete details, see reference.md.
MIDI Message Structure
- Note On:
[0x9n, note, velocity](n = channel 0-15) - Note Off:
[0x8n, note, velocity] - Control Change:
[0xBn, cc, value]
Note Mapping
| Region | Notes | Purpose |
|---|---|---|
| Pad Grid | 0-63 | 8x8 RGB pads (row * 8 + col) |
| Track Buttons | 100-107 | Red LEDs |
| Scene Buttons | 112-119 | Green LEDs |
| Shift | 122 | No LED |
| Faders (CC) | 48-56 | CC 48-55 + Master 56 |
MIDI Channel Effects
| Channel | Effect |
|---|---|
| 0-6 | Brightness 10%-100% |
| 7-10 | Pulse animation |
| 11-15 | Blink animation |
Use channel 6 (0x96) for full brightness.

F0 47 7F 4F 24 00 08 [pad] [pad] [R-MSB] [R-LSB] [G-MSB] [G-LSB] [B-MSB] [B-LSB] F7
RGB encoding:
const encodeRGB = (value: number): readonly [number, number] =>
[(value >> 7) & 0x01, value & 0x7F] as const;
