![]() The Launchkey Mini has 18 controllable LEDs: two rows of 8 drum pads, and two round buttons. ![]() The LEDs are controlled using a “note on” command on MIDI channel 1 (byte 0x90), where the “note” is the LED to control, and the “velocity” is the color to set.īe aware that a respective “note off” command will not turn off the LED, you need to send an additional “note on” command with the off color. The LEDs are numbered sequentially from left to right. On the top row, the LEDs start at note C6 (96) and end at note G#6 (104). # This is a sweep animation to demonstrate control of the Novation Launchkey Mini On the bottom row, the LEDs start at note E7 (112) and end at note C8 (120). The script will generate a random color from the LED palette Midi_out.send(_bytes()) # Disable "InControl" mode Midi_out.send(_bytes()) # Switch to "InControl" mode Midi_out = mido.open_output("MIDIOUT2 (Launchkey Mini) 2") # Launchkey InControl port Random.randint(int(not red_or_green), 3) * 16 Return random.randint(int(red_or_green), 3) \ Red_or_green = bool(random.randint(0, 1)) # Making sure the number is always >0 for one component Midi_out.send(mido.Message('note_on', channel=0, note=led_id, velocity=color_vel)) Leds = row1 row2 # LED indices, combined # that sweeps from left to right across the available LED pads. To recap: in order to control the LEDs on your Novation Launchkey Mini II, you need to connect to the second MIDI output port and set InControl mode to “on” (either via Ableton or using the special message 0x90 0x0C 0x7F). Then to change colors you use another “note on” message where the LED position is your “note” and the color of choice is your “velocity”. ![]() If you found this post helpful, like, follow, and subscribe check out some of my other projects. When I was originally fiddling around with this, I figured out I could get the LEDs to respond to messages from Ableton so long as the “InControl” mode was enabled, and yet I couldn’t switch the device into “InControl” mode without having Ableton open. #RENOISE TUTORIAL MIDI IMPORT SOFTWARE#. ![]()
