I hear you on the MIDI stuff, but again: most MIDI targets only use channel-cc (control change) and Note-On/Note-Off. So if you read up on those, you're pretty much introduced. Also note that in most contexts, the CC numbers don't mean anything in particular. After that, there are just "other message types," including bank select, program change, sysex, NRPN and even some that MIDI Designer doesn't implement (RPN is the only one I know of)... anyway, good luck and feel free to come back with more specific questions... Congrats on the 76 thing, I hear that's when the wisdom coalesces...
