Show HN: FOSS Guitar Karaoke (With Lights)

This is pretty sweet. Demo video really helps to explain the concept. It's like what I imagined my friends and I doing while playing Rockband...if we were talented enough to play real instruments. Seems like one of those things that you can't imagine a future without. Nice work @fivedogit

Favourited, this is really cool. It's what I hoped Rocksmith 2014 could do but can't.

That’s pretty cool. Great work. What needs to be done to make this so that an average person could use it?
