A synth engine in Rust that plays songs written as text. Edit the file and it changes on the next bar; plug in a MIDI controller and the knobs move it live.

CRT sound visualizer

A music visualizer in the spirit of Windows Media Player's, on an ESP32. A microphone listens; the picture goes out as composite video to an old TV. A hand near the antenna bends it.

Source goes public soon.

drumgen

A deterministic drum generator that tries to sound alive. Rules and probability over curated pattern banks, not a model.

Source goes public soon.

On hold until I can buy MIDI banks played by a real drummer.
