i have a korg pa600 . i did a intro and verse1 and chorus just playin around to see if it can be done . it can be done . seems to me it would be better if you would do a midi file. the intro and verses has to be recorded and programmed in minor mode. the chorus has to be programmed in major chord mode. this way the "wrap around" would work right in any key.alot of work for one song.
