I dunno. I just recorded a song onto disk on my PSR-740 and then read it into Cakewalk and it mapped onto all the correct channels. I have found, though, that if you record directly into Cakewalk from the keyboard, you have to set the channel to omni otherwise it doesn't set the instruments correctly. The probable reason for transposition is that the PSR doesn't know which key you're playing in and therefore doesn't put the key signature into the midi file. Cakewalk doesn't know the key either when it reads the file. One way round this is to set the key signature into the file once you have it loaded into Cakewalk.
