A Revival of ToneMatrix by Audiotool
ToneMatrix Redux is an HTML5 revival of the flash game ToneMatrix by Audiotool. It’s written in JavaScript, using the Tone.js synth library. ToneMatrix Redux includes a custom particle engine, as well as a song sharing system.
In 2021, Camilo Mejia forked this project to create Procedural ToneMatrix (GitHub), which can generate songs using several random algorithms.
