Please Help me out... I would like to learn what Midi files can be downloaded from the internet and played on Pianomation or Pianodisc systems. If the file is of "midi" type and plays piano when played from a computer (Media player) will it work on one of these or both systems? Also, Is there some sort of conversion that one can do to play Pianodisc files on Pianomation and vice versa? I have searched around and still can't figure this stuff out!
