You've received some good responses to your question, so I'll just turn
you on to a couple of MIDI resources that you may find useful.

"The MIDI Technical Fanatic's Brainwashing Center" at
http://www.borg.com/~jglatt/ has just about everything one might need to
know about MIDI.

"The Urge To Merge" at http://home.comcast.net/~mrkesti/ This site provides
schematic, source code, and more concerning one of my MIDI projects that
implements an 8051-based merger with footswitch inputs and relay outputs.

Have fun! MIDI is definately a pleasant medium with which one can bring
one's music and embedded processing skills together!
