Casio CZ/ VZ/ FZ - Pro Series

I don't calim to be an expert in electronics, but I know that the 
optoelectronic coupler on the MIDI port actually died in my Bit 01 a 
while ago, and it was a $6 part that my friend successfully 
installed for me. If the unit seems healthy otherwise (like you can 
change and edit patches and store them to memory), but the MIDI 
functionality is gone, that could be one possibility.

Also, my VZ-8m behaved erratically when the backup battery died, you 
might want to check it as well. I recommend buying a small plastic 
enclosure for a AA or AAA battery (can be attached to the circuit 
board with double sided mounting tape) and a lithium cell in that 
format. It will last literally a lifetime. I've done this mod on my 
unit.

regards

Maxim
