Have a look at the latest version of SuperSonic, exploring running scsynth on a webpage. as a worklet. With the release today of version 0.34.0 it just got a lot more fun to play with.
Sam Aaron is doing a wonderful job in developing it
I’ve also built it from source on both my mac-mini and on a raspberry pi5 to run locally. Works great.
Try running several versions on different web pages simultaneously!
