I Turned an Old Keyboard into a Midi Controller

I turn a cheap, old, charity shop (thrift store) electronic keyboard piano into a cool midi controller. I added drum pads, including one that can be used as a kick drum, that operate on a different midi channel to the keyboard, so that I can play two instruments with the midi controller at the same time. I also added a joystick for pitch bend and control change midi messages. Circuit diagram and code: https://github.com/hanomaly/old-keybo...
