Casio CZ/ VZ/ FZ - Pro Series

Sounds like it could be eitehr the RAM or perhaps the interface. I 
discovered I have bent pins in my CZ-1.  I have used the EZ-CZ 
cartridge with success; never had an RA-3.

Space aliens and bells sounds like the patches you get by stuffing a 
peset with "illegal" data via sysex. Not sure what would cause that in 
ram cartridge.

Do you get the same alien sound repeatedly in specific ram slots?  
(That is, does ram preset 4 always sound the same?) That may give you 
some clues as to where the problem is.
