hardware/teensy/ — PlatformIO firmware. Notes 0–125 set one color channel of one pixel (note/3 = LED, up to 42 pixels; note%3 = R/G/B, value = velocity×2, velocity 1 writes 0), note 127 latches the frame. One build fits any strip length.ableton/ — the LumiDI Max for Live MIDI effect: solid / pulse / chase / rainbow animations, HSV color, brightness, speed, tempo sync, per-strip pixel count, and multi-strip layouts (several devices rendering one animation across their strips). See ableton/README.md.web/ — the landing page plus a browser strip simulator (under /simulator/) that listens to the same MIDI stream. See web/README.md.python3 ableton/build_amxd.py, then drag ableton/LumiDI.amxd onto a MIDI track.web/README.md) to preview.
