Love the details for completeness, like modes, and your discussion of adjustments you found necessary along the way. Great job on the project and great explainer video too.

Slight tangent--I've often wondered if the principles behind audio keyloggers, where you record typing sounds and try to reconstruct what was typed, could be used to make a wireless computer keyboard that never needs batteries. Seems like you're attacking an inverted version of that problem.

Interesting stuff, thanks!

That's a really cool angle. As a matter of fact I'm working on a system like this only that it uses FFT to get the notes instead of midi.
