From the project

A MIDI sequencer using marbles.

MIDI Marble Sequencer is a hardware + firmware project that detects marbles on IR sensor tracks and outputs MIDI over USB. The system is split into a main ESP-IDF firmware (sequencer + USB MIDI) and ESP32-based control boards (Arduino/PlatformIO) connected over I2C.
