Launchpad/PRG/04 Controlling the Surface/06 LED Lighting SysEx

• LED lighting SysEx message

  • One SysEx message can light many LEDs. LED indices are always the Programmer Mode numbers, whatever layout is selected.
    • Hex: F0h 00h 20h 29h 02h 0Eh 03h <Colour Spec> [<Colour Spec> ...] F7h
    • Decimal: 240 0 32 41 2 14 3 <Colour Spec> [<Colour Spec> ...] 247
  • Each <Colour Spec> is a lighting type byte, an LED index byte, then 1-3 bytes of lighting data.
  • Lighting types:
    • 00h (0) static: 1 byte, palette index
    • 01h (1) flashing: 2 bytes, colour B then colour A
    • 02h (2) pulsing: 1 byte, palette index
    • 03h (3) RGB: 3 bytes, red, green, blue, each 0-127
  • A message may carry up to 106 Colour Specs, enough for the whole surface.
  • Example in Programmer layout: F0h 00h 20h 29h 02h 0Eh 03h 00h 0Bh 0Dh 01h 0Ch 15h 17h 02h 0Dh 25h F7h (240 0 32 41 2 14 3 0 11 13 1 12 21 23 2 13 37 247)
    • Pad 11, the bottom-left pad: static yellow (13).
    • Pad 12: flashing between 21 and 23, dim and bright green.
    • Pad 13: pulsing turquoise (37).
