If you're interested in algorithmic music generation, you might want to try Glicol's web demo at:

https://glicol.org/demo#ambienthouse

It's a browser-based tool that lets you experiment with algorithmic composition and sound synthesis.

Wish the videos were working. It would be really cool to adjust the style as well

We've been using Earsketch with students: https://earsketch.gatech.edu/

But when we tried to self-host or do an offline version, it was impossible to find the library. Perhaps it isn't open-source.

Thanks to the links in this thread, now I have some other projects to try instead.

Mercury is also pretty sweet as a live coding environment: https://github.com/tmhglnd/mercury

piggybacking on the title to feature an album of generated music I released yesterday (using a different system I handrolled in typescript + rust):

Overtone is the state of the art if you like Lisp https://github.com/overtone/overtone

This is interesting. What I would have sold me the idea is a screen recording of someone programming and playing a few examples.

The videos do not work, what is a pity, I really would like to hear some results!

Would it be easier to just provide simple audio files?

Very cool
