## Brightness Control via MIDI Channel

The same velocity color appears at different brightness levels:

| Channel | Brightness | Usage |
|---------|------------|-------|
| 0 | 10% | Very dim |
| 1 | 25% | Dim |
| 2 | 40% | Low |
| 3 | 55% | Medium-Low |
| 4 | 70% | Medium |
| 5 | 85% | High |
| 6 | 100% | **Full** (recommended) |

Example: Red at different brightness levels
```typescript
output.send('noteon', { note: 0, velocity: 5, channel: 0 }); // 10% red
output.send('noteon', { note: 0, velocity: 5, channel: 3 }); // 55% red
output.send('noteon', { note: 0, velocity: 5, channel: 6 }); // 100% red
```

## Animation Effects via MIDI Channel

| Channel | Effect | Rate |
|---------|--------|------|
| 7 | Pulse | 1/16 note |
| 8 | Pulse | 1/8 note |
| 9 | Pulse | 1/4 note |
| 10 | Pulse | 1/2 note |
| 11 | Blink | 1/24 note |
| 12 | Blink | 1/16 note |
| 13 | Blink | 1/8 note |
| 14 | Blink | 1/4 note |
| 15 | Blink | 1/2 note |

Example: Pulsing red
```typescript
output.send('noteon', { note: 0, velocity: 5, channel: 9 }); // Red pulse 1/4
```

## Custom RGB via SysEx

For precise color control beyond the 128-color palette:

### SysEx Message Format
```
F0 47 7F 4F 24 00 08 [pad] [pad] [R-MSB] [R-LSB] [G-MSB] [G-LSB] [B-MSB] [B-LSB] F7
```

### RGB Encoding Function
```typescript
function encodeRGB(value: number): [number, number] {
  // Split 8-bit value into MSB (bit 7) and LSB (bits 0-6)
  const msb = (value >> 7) & 0x01;
  const lsb = value & 0x7F;
  return [msb, lsb];
}
```

### Complete Custom RGB Function
```typescript
function setCustomRGB(
  output: Output,
  pad: number,
  r: number,
  g: number,
  b: number
) {
  const [rMSB, rLSB] = encodeRGB(r);
  const [gMSB, gLSB] = encodeRGB(g);
  const [bMSB, bLSB] = encodeRGB(b);

  output.send('sysex', [
    0xF0,                   // SysEx start
    0x47,                   // Akai manufacturer ID
    0x7F,                   // Device broadcast
    0x4F,                   // APC Mini MK2 product ID
    0x24,                   // RGB LED command
    0x00, 0x08,             // Length (8 bytes)
    pad, pad,               // Start/end pad (single pad)
    rMSB, rLSB,             // Red
    gMSB, gLSB,             // Green
    bMSB, bLSB,             // Blue
    0xF7                    // SysEx end
  ]);
}
```

### Range RGB (Multiple Pads)
```typescript
function setRangeRGB(
  output: Output,
  startPad: number,
  endPad: number,
  r: number,
  g: number,
  b: number
) {
  const [rMSB, rLSB] = encodeRGB(r);
  const [gMSB, gLSB] = encodeRGB(g);
  const [bMSB, bLSB] = encodeRGB(b);

  output.send('sysex', [
    0xF0, 0x47, 0x7F, 0x4F, 0x24,
    0x00, 0x08,
    startPad, endPad,       // Range of pads
    rMSB, rLSB,
    gMSB, gLSB,
    bMSB, bLSB,
    0xF7
  ]);
}
```

## Common Color Examples

```typescript
// Primary colors
setCustomRGB(output, 0, 255, 0, 0);     // Red
setCustomRGB(output, 1, 0, 255, 0);     // Green
setCustomRGB(output, 2, 0, 0, 255);     // Blue

// Secondary colors
setCustomRGB(output, 3, 255, 255, 0);   // Yellow
setCustomRGB(output, 4, 0, 255, 255);   // Cyan
setCustomRGB(output, 5, 255, 0, 255);   // Magenta

// Pastels
setCustomRGB(output, 6, 255, 182, 193); // Light Pink
setCustomRGB(output, 7, 173, 216, 230); // Light Blue

// Brand colors
setCustomRGB(output, 8, 29, 185, 84);   // Spotify Green
setCustomRGB(output, 9, 255, 69, 0);    // SoundCloud Orange
```

## Peripheral Button Colors

Track and Scene buttons have fixed colors:

| Button Type | LED Color | On Velocity | Blink Velocity |
|-------------|-----------|-------------|----------------|
| Track 1-8 | Red | 1 | 2 |
| Scene 1-8 | Green | 1 | 2 |

```typescript
// Track button on
output.send('noteon', { note: 100, velocity: 1, channel: 0 });

// Scene button blinking
output.send('noteon', { note: 112, velocity: 2, channel: 0 });
```
