Mini UNTZtrument Midi Controller - Pro Micro Remix

This is my Remix of the Mini UNTZtrument from Adafruit (https://www.thingiverse.com/thing:409733)

I added a ProMicro mount - since they have the Leonardo boot-loader and similar pin-out.

I also slimmed the case down a bit, since the micro is significantly smaller than the Leonardo was.

The only addition to the existing instructions (https://learn.adafruit.com/mini-untztrument-3d-printed-midi-controller/3d-printing) is to use the TeeOnArdu board library in the Arduino IDE

I included my sketch, but its unchanged from the one on the Adafruit site
