I have a PDS 128Plus system.  When my home was being built, I inquired
with my retail store on how to utilize my central stereo system for the
PianoDisc CD's.  I installed two special cables from my stereo to the
piano to provide the digital control signal.  That works fine.

The problem is that the PianoDisc CD does not seem to play the same way
as a normal CD.  I have hooked it up directly to the CD player and with
a 'Y' from the output.  I still only get the digital piano signal to
the piano but no accompanying music through the system.  What am I doing
wrong?
