Hey, I've got the complete schematics for the MIDI interface project online now: http://littlebluerodent.tripod.com/MIDI/Midi.htm Warning: No actual hardware has been built from these schematics yet, so there's a strong chance a few errors may exist. No drivers have been written either, but unless someone points out something wrong with the schematics, that'll be the next stage. Any comments on this or the sequencer yet? - Cyan
