Laser Harp I

I put together a merged version of the firmware the other day, where the switch on pin 2 lets you select either scale (pot selectable) or chords (keyboard) mode. Also added a separate transpose function for the keyboard, stepping in fifths.

Also ditched the legacy DIN MIDI. Thinking of using pin 1 for transposition indication LEDs above the keyboard.

And there are new videos on my Instagram :)

Edit: New videos on YouTube too.

A combination of errors confusing me, but I finally got it right! The prototype keyboard isn't very pretty, but it works :)

Well, there are issues I need to address, but I've managed to get limited functionality at least. I will have to take another look at the keyboard matrix hardware, and also check my row scanning. Could be just too long wires between keyboard and Teensy, because the functionality of individual keys is erratic. Also I can't get the chord selection to work properly, but that might be a related issue. Maybe I'll just put together another keyboard. The one I'm using now is based on a discarded mechanical keyboard prototype I made. I don't trust it. Anyway, I made a teaser video for you.

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.

Just a short clip for now...
