This is such a great use case. I stand in front of my monitor with my guitar and have to scroll the sheet music. So that means stop playing. I often wander away from my computer and then come back if I forget how a section goes.

I'm using tabs not notes, but I'm assuming/hoping your solution will adapt quite easily.

I wonder if you could use a microphone to listen for the notes in order to get auto-scrolling. Because you know the general timing, you're not searching through the entire song (likely) but honing down on the exact point that person is at. An inobtrusive metronome might be nice to.

Congats! One of the best projects I've seen in a long time, and particularly such a good use case for the early stage of this hardware.
