Yes, that is probably the way to go, I only wished I had a PBP programmed USB device that would do MIDI...
The information about the PIC2 programmer gives a lot of information, but it doesn't do MIDI, so it is not a good example for a descriptor file.

I have a feeling that I am reinventing the wheel... Come on, this must have been done before I suppose?
(Or did nobody ever use PicBasic to do MIDI communication?)
