Hello everyone !
I made Tuple, a free open-source Max for Live MIDI device for Ableton Live.
It shows every in-key chord, plus borrowed chords, on one color-coded grid. The goal is not to generate progressions automatically, but to make harmony visible and playable while staying inside the Ableton workflow.
It supports Live key/scale sync, voice leading, Smart Chords, 28 voicings, Push 2, MIDI mapping, and progression capture to MIDI clip.
