If all you need to do is is set cis to be a different pitch from des, that's quite easy. I think that all you need to do is set different alterations in the file lily/pitch.cc. Of course, you will need to be able to compile lilypond to do this. >> >> I don't know anything about pd's internals, but I have some rusty >> programming knowledge.

There would be *lots* of people interested in better MIDI. If you were interested and willing to take it over, that would be great. The problem is that right now, nobody is a champion for MIDI output.
