I was just working on a music improv app for the MacBook trackpad [1] and tried to use Sonic Pi 4 for the backing track (muse) generator but it was too clunky to run a full fledged second GUI alongside the app and control it through OSC.

I had to do sample retrieval, decoding, native CoreAudio logic to get acceptable latency. A programmable synth would have made my life so much easier.

supersonic-scsynth in Pi 5 feels more fit now, it’s the first time I tried a JS frontend for a macOS app but if it lets me import this and use it so easily, it already paid its dividends.
