This is the standalone version of the music system created for Bird Ladies, a narrative game still in development.
A devblog article is coming in a few months to explain how it all works.
In the meantime, feel free to play around with it. Share your best melodies, use it with your favourite silent movie, or use it as dynamic music ambience for a fancy tabletop role-playing game ;)
