Not sure if looking for README feedback, but I think a ~30 second video with sound would help get an idea a lot.

Mmm, the readme is an impenetrable unorganised wall of text that jumps between broad high level things, and tiny intricate internal technical details.

All in all this feels a bit early to really show off. A recorded demo video would be good. Also, imo, the demo song should be setup in a way that it just plays out of the box.
