I designed this MIDI controller for my friend, who uses the Looper device in Ableton Live extensively. It’s a grid of 12 light-up buttons designed to control four tracks:
The yellow buttons mute and unmute The red buttons arm the tracks The blue buttons start and stop record/overdub on the Looper device The V1 LoopBox I designed the first version several years ago. It relied on a Teensy dev board.
