Casio CZ/ VZ/ FZ - Pro Series

howdy,

 Iwould start out with a nice CLEN pot, 50k is probably all right,
Go into the pitch bend ranges on the front panel, testing different 
settings. Then and only then would I go inside. I'd like to gat a 
service manual for a CZ-101, also a CZ-1, Also a CT-270. That would 
make things fun. I STILL use a pair of the TB-1, the 2x8 "midi 
through box" as they called it, they have never failed me. Using old 
junky wall warts, dropping, whatever. Of course, that's  just part of 
my midi switching system, but they were the first and still going 
strong.
