I went to a basement party/rave recently where the DJ was live-coding strudel, was incredibly cool to see in person. people would watch them type out new lines in anticipation of a beat drop

Pretty cool to see this post, I had no idea where to find more info about it!

Another live-coding environment that is quite nice (Haskell-based) is TidalCycles: https://tidalcycles.org

I wrote a whole album of material about 10 years ago with it, just remastered/re-released it. It's a fun way to write music while on an airplane!

Strudel is TidalCycles but in javascript.

yeah, but TidalCycles doesn't have the interactive code that shows you what is playing or have inline sliders :P

Strudel doesn't have all of the advanced features of TidalCycles. It really just depends on what you need. Strudel is easier to get started with, and definitely more visual/immediate, but TidalCycles has the full power of Haskell, longer history, and more advanced tooling. Either way, it's really nice to see people getting more involved in programmatic music, regardless of which tool they use. :)

It's fun to watch and somehow more approachable to me than a big program with lots of menus and virtual knobs.

Would be curious licensing on music you produce with it eg. can you use it, record the session then put it on YT no copyright.

Algorave definitely seems to be having a moment! I know the scene has been around for a while (live chiptune shows have been a thing for years), but it seems like the Strudel-specific live coding shows are rapidly becoming popular. I love to see it. As someone who likes both programming and music, it's awesome to see people mix both and get fantastic results.
