The problem with the diskette error message sounds like a bad disc
drive.  Usually this happens when a diskette is removed at the same
time it is being read, thus misaligning everything.  It is easy to
replace but the drive is available only from PianoDisc.  A drive from
a computer store won't work.  Contact a PianoDisc service tech in your
area.  He probably has one on hand and can install it for you.

By the way, never press the eject button while the piano is playing.
Always press Pause or Stop first.  You may notice the light near the
slot.  When it is lit (which is often), the diskette is being read.
Think of ripping the needle across your old LP's, only worse.  That's
what can happen if you eject a disc while the light is on.
