Sonic Pi is really fun to play around. However, the editor is fucking abysmal and turns me off every time I try to use it, since I can't use my muscle memory to copy/paste/multiselect and have to otherwise learn another set of keybinding that make no sense whatsoever (instead of CTRL-X to cut you have ALT-X, for example). I wish I were able to use VSCode. I know an extension exists, but it only sends the current file to the Sonic Pi session and has no autocompletion, which is fairly necessary during a live-coding music session to keep the tunes flowing. If I'll ever get around to understand how to develop an extension I'll try my hand at it, I guess.
But otherwise yeah, it's some good stuff and has lots of unexplored potential.
