I have an old PianoDisc PDS-128Plus which uses a floppy diskette
drive which I am planning to upgrade to the new wireless IQ system.
I have a few dozen PianoDisc floppies which I plan to convert to
the new system with the PianoDisc conversion program.  I also have
a few non-PianoDisc floppy disks that PianoDisc will not convert
(Sergei Rachmaninoff: The Complete Recordings, from the Immortal
Pianists Series, for example, among a few others).

Years ago I bought the DOS based PianoDisc software for downloading
and converting MIDI files into PianoDisc files and vice versa, but
the software doesn't recognize the files when I try to open them in
my external floppy disk drive.  How can I get these non-PianoDisc
diskettes converted?  Thanks!
