When I was messing around switching scales while playing the harp, I realized that if I instead used keys or buttons to select scales, and replaced the scales with chords that could be strummed, I would have a laser autoharp or omnichord. It just had to be done.

Today I got a first sketch done, and now I just need to build a keyboard for it so I can try it out. Hopefully I'll get time on my hands to do that this weekend.

If you are curious, you can check out the code in its current state on Github.
