I have a PSR 740 since some days ago and I have seen there is no possible way to edit the lyrics and/or the chords at the MIDI files. My question is, is there any way to do this? If there is a program for PC please tell me. I have read that the PSR 9000 can edit this kind of stuff with a keyboard attached to it, but I have also read that the PSR 9000 is too expensive and too bad for its price!!
