Does anyone know how to write "Instrument Definitions"? Is it something that's hard to do? I can't find any on the web for my Roland RS-70, and I'd really like to have them for Cakewalk. I can use the standard GM1 and GM2 sounds, but I want to use the preset patches too, user patches, drum patches, and user drum patches as well.

Anyone ever do this and have any tips?
