FM / 6 — I made a six-operator browser synth in an evening

I made this in an evening with the new Astra, if anyone is interested.

Six operators, two keyboards — a sound you can take apart. It runs in the browser (WebAssembly + Web Audio). Start with a bell, a bass, or a slowly moving chord. Change the operators and hear how the sound is made.
