Dnj....Sorry, don't know how to do that. I don't use a computer in my recording and the cd's I master are cda format, unless I can somehow convert to midi, wav, mp3 or whatever. In any event, I've tried before unsuccessfully, and the format that my Korg creates cannot be read on a computer, or at least I don't know how to make a copy that can be read. Tried Pyro once unsuccessfully.
