Acoustic playback is a piano-only performance.
Symphony disks by PianoDisc contain a piano performance with orchestrated accompaniment which is heard through speakers. Some professional keyboards utilize other disk formats. Remember that the file must be standard MIDI Type 0 and that you must define the piano part. For more information about playing standard MIDI files on your PianoDisc system, please see the additional documentation provided on our web site. If you are using a PianoDisc diskette, the produced feature will let you set the order that songs are played.
