Quick and Dirty Arduino Midi Over USB

A lot people use arduinos as a starting point for diy midi controllers. A perfectly reasonable assumption many of them make is that you can use the on board usb port to send midi data to your computer. While you can send serial data, it is not possible for your computer to recognize this as midi messages right out of the box.

Calculator MIDI USB Controller

Borderline useless, more trouble than its worth, but cool nonetheless.

Make cool things look as nerdy and boring as possible!

One of the first things I thought of doing with an arduino was turning an old calculator into a MIDI controller. The buttons are simple momentary switches.. no velocity sensitivity, but its nice for a pretty compact set of buttons.. and it looks neat. stfu.
