Disklavier

Hello all

Are there any programs available for editing the files on the floppy disks 
that control units like the DKC500RXG generate?  The program that is 
available for the E-SEQ disks that is in the files section of this group is 
great for the E-SEQ disks.  I would like to have more meaningful disk and 
song titles than PIANO001.MID etc on my MIDI disks.

Any help would be most appreciated.

Regards John
