Doodle Your Own Generative Music in the Browser with Musical Spirograph

Terrence O’Brien reviews Musical Spirograph, a browser-based toy that uses rotating rotors and rings to trigger notes, with six rotors, up to three drawing arms, six scales, six synth presets, and BPM/quantization controls; the sound engine isn’t perfect and it lacks MIDI out, but it’s soothing, hypnotic, and fun to explore.
