TL;DR
Paul Cunningham has created an impressive 8-track MIDI (Musical Instrument Digital Interface) sequencer using the Adafruit PyGamer, a fun handheld gaming device. This project stands out not just for its creativity but also for how it pushes the boundaries of what you can do with the PyGamer's hardware. Paul dove into this project while snowed in, and it’s a great showcase of how CircuitPython, a version of Python designed for small microcontroller boards, can be utilized to bring musical ideas to life.
