I’m working on a spatial language for music production called Hyperstep. As I was building a tool to visualize drum samples and tones, I realized it could be good enough to share on its own.
You can try it here: https://a-sumo.github.io/hyperstep/
The code is open source and can be found here: https://github.com/a-sumo/hyperstep
There may be issues running the demo Linux and on large audio files.
I hope to solve these issues shortly.
