Launch Ableton Live clips with the MacroPad RP2040! Mechanical keyswitch clip launching is now a reality. Sync NeoPixel LEDs with your Live session via USB MIDI.

All coded in CircuitPython and customizable to suit your needs. It's the tiny little Launchpad or Push you've always dreamed of!

The basic code concept can be adapted to Pure Data with r_cycle or Max/MSP.

Sync with MIDI

One of the coolest things about this project is how you can keep the MacroPad and Ableton in sync so that any clip launched in the software UI will light up the related keyswitch LED. This is accomplished with bi-directional MIDI messages.

For example, when Ableton launches a clip, it sends a MIDI message to the MacroPad to say "hey, turn the LED green, this clip is running!" It doesn't matter if the clip was launched with the hardware or software, Ableton takes care of all the LED MIDI message logic. In fact, it even encodes the LED color in the MIDI message. Clever!
