• MIDI on Launchpad Pro [MK3]

  • The Launchpad presents three USB MIDI interfaces. On Windows they appear as the first, second, and third interface.

    • LPProMK3 DIN In/Out: MIDI passed to and from the DIN ports.
    • LPProMK3 DAW In/Out: DAW and similar software driving Session mode.
  • The Launchpad sends Note On (90h-9Fh) with velocity 0 as its Note Off. It accepts either Note Off (80h-8Fh) or Note On with velocity 0.
  • Launchpad/PRG/03 MIDI/01 Device Inquiry

    • Device Inquiry message

      • The Launchpad answers the Universal Device Inquiry SysEx.
      • Host to Launchpad: F0h 7Eh 7Fh 06h 01h F7h (240 126 127 6 1 247)
      • Reply from the application: F0h 7Eh 00h 06h 02h 00h 20h 29h 13h 01h 00h 00h <app_version> F7h (240 126 0 6 2 0 32 41 19 1 0 0 <app_version> 247)
      • Reply from the bootloader: F0h 7Eh 00h 06h 02h 00h 20h 29h 13h 11h 00h 00h <boot_version> F7h (240 126 0 6 2 0 32 41 19 17 0 0 <boot_version> 247)
      • <app_version> and <boot_version> are four bytes, one decimal digit (0-9) each, matching the version shown on the bootloader's green pads.
  • Launchpad/PRG/03 MIDI/02 SysEx Format

    • SysEx message format used by the device

      • Every Launchpad Pro [MK3] SysEx message, in either direction, starts with this header:
        • Hex: F0h 00h 20h 29h 02h 0Eh
        • Decimal: 240 0 32 41 2 14
      • 00h 20h 29h is the Focusrite/Novation manufacturer ID, the same bytes that appear in the Device Inquiry reply.
      • A command byte follows the header and selects the function. Launchpad/PRG/06 SysEx Command Summary lists the commands.
  • Launchpad/PRG/03 MIDI/03 Selecting Layouts

    • Selecting layouts

      • A layout is the view shown on the surface. The device's own buttons select layouts, as does this SysEx message:

        • Decimal: 240 0 32 41 2 14 0 <layout> <page> 0 247
      • <layout> values:

      • The Launchpad also sends a layout-select message whenever its view changes, so a host can follow the user's navigation.

      • Note/Info The Sequencer Projects, Sequencer Patterns, Custom Mode, and Custom mode Settings entries only switch what the surface shows. The guide documents no message that reads or writes Project, Pattern, or Custom Mode contents.
