DIY MIDI Keyboard Encoder

"This is going to be part of a project which will add a full size keyboard to a Korg Monotron, along with other modifications. It is a two octave keyboard (which was liberated from a well and truly ruined keyboard controller). The control circuitry was built by me on stripboard, and uses a pre-programmed PIC microcontroller bought from http://picsynth.000space.com/midi.html
Although it does not use velocity sensitive keys, the fixed velocity can be set using a potentiometer. I had to assemble a new circuit board which was attached under the keys, on which were 24 tactile switches. As a key is pressed, it closes the switch. The keys are arranged in a 2 * 12 matrix, although the PIC software supports up to a 4 * 12 matrix.
The sounds in the video are generated from some of the softsynths that come with GarageBand."
