The project looks interesting. Screenshots would help, as well as a link to the demo at https://signal.vercel.app/edit. The demo asked for MIDI permission, but didn't accept input from my MIDI keyboard until I realised you have to enable it in settings. There's enough lag in the system that most of my notes end up a bit delayed, and the snap-to-grid doesn't seem to be working.

Please consider changing the name. A generic common word is hard to search for, and there is already well-known software named Signal.
