The language certainly looks nice! Is it open source? I think it makes sense for this kind of tool, since it's inherently "hackery". I mean people who want to write music with code also probably want the ability to understand and modify any part of the stack, it's the nature of the audience.

I'll shamelessly plug my weirdo version in a Forth variant, also a house loop running in the browser: https://audiomasher.org/patch/WRZXQH

Well, maybe it's closer to trance than house. It's also considerably more esoteric and less commented! Win-win?
