Lindoz, I've never used midi songs for spare parts, because I thought the sound was shallow and tinny. However, if the sound will come out with the quality of the kn6k, then maybe it's time for me to reconsider. After all, there must be a few million midi files to chose from by now. I have always relied on keyboard styles to provide the pieces, but when you have to rebuild the variety note by note, adding instruments here and there, the time involved grows and grows. I'm glad I don't have to do this for a living - I'd starve!
