The visual workspace for music teachers and creators. Turn live MIDI and audio into chord, notation and audio-reactive visuals then record video, audio or MIDI natively. Stream to OBS, TouchDesigner and Resolume for live performance.
I'm a jazz pianist turned computer scientist / builder. I used and looked for pretty much every piece of software to visualize harmony and audio and always had tons of problems with them. So when I got the skills to build something better, I did.
This is the result of me taking every quarrel and desire I had over the years and turning them into a reality.
There's still a lot I need/want to build and I would love to hear some of your ideas for features and things that might be good for this project.
