I have a PSR530. I would like to create complete songs using the auto arranger, etc. and download it onto a PC for editting. I just purchased the midi kit from MIDISOFT with the cables, and recording software but I can only record individual tracks that I play while the software records. Can't I transfer complete songs. I'd especially like to transfer some of the demo song and edit those. Is it the software, a MIDI limitation, or my lack of knowledgge?
