Re: Service Manual in PDF? Casio CZ5000/CZ1/CZ3000

2007-11-01 by narfman96

The CZ-1 is the only synth in the CZ line that comes with aftertouch 
even though all it does is activate the vibrato. The CZ-1 is also 
velocity sensitive and the patches scale the DCO, DCW, and DCA from 0-
15. All of the patches from the other CZ's will load but they will 
have these parameters set to 0. The CZ-1's patches will work in the 
other CZ's. They will ignore the velocity settings.

I tried the SY22 aftertouch strip but it was too narrow from front to 
back at 1/4 inch. The black and white keys hit the original strip in 
2 different areas 1/4 inch apart. The original strip is almost 3/4 
inch wide. 

I did figure out what is wrong with the aftertouch though. There are 
rubber strips that have 4 rows of very fine carbon vanes that make 
the connection between 2 stainlees steel bands that run under the 61 
keys. There are 3 rubber strips 12" long to span the distance. The 
entire assembly is sandwiched by felt glued to foam rubber. It's 
mounted in a plastic strip and held in with 2 sided tape. One of the 
rubber strips has become non-conductive from the drink that was 
spilled in it before I purchased the synth. A portion of the foam 
rubber is bad too. I may try getting some of the conductive paint 
that restores the carbon. I tried a soft lead pencil but it wouldn't 
work.

I also scanned the CZ5000 Service Manual if anyone wants it. It's 60 
pages and 9.8 mb. It explains a lot of the circuitry and why the CZ 
sounds like it does.
