name: color-palette-ref description: APC Mini MK2 color palette reference with velocity values and custom RGB via SysEx. Use when user asks about "color", "velocity value", "RGB", "palette", "brightness", "LED color", or needs to set specific colors on the APC Mini MK2.

APC Mini MK2 Color Palette Reference

Complete reference for the 128-color velocity palette and custom RGB control.

Primary Colors (Quick Reference)

Extended Color Palette

Reds (Velocity 1-8)

Oranges/Yellows (Velocity 9-16)

Greens (Velocity 17-28)

Cyans/Blues (Velocity 29-48)

Purples/Magentas (Velocity 49-64)

Brightness Control via MIDI Channel

The same velocity color appears at different brightness levels:

Example: Red at different brightness levels

Copyoutput.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

Example: Pulsing red

Copyoutput.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

CopyF0 47 7F 4F 24 00 08 [pad] [pad] [R-MSB] [R-LSB] [G-MSB] [G-LSB] [B-MSB] [B-LSB] F7

RGB Encoding Function

Copyfunction 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

Copyfunction 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)

Copyfunction 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

Copy// 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:

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

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