I have a PD128+ with symphony option.  I would like to play PD CDs
through the system, but only have a couple of portable CD players
with line out or earphone outputs.

Can any of these be used?  How?  If not, what do I need?  I've
tried and have been unable to control the piano using what I have.
Obviously doing something wrong.

Thanks in advance for the help,
