Casio CZ/ VZ/ FZ - Pro Series

Congratulations on your lucky find.  I am familiar with the CZ-1000, 
CZ-5000, CZ-1, and VZ-8m.

On any of the CZs, you can (via sysex dump) put numbers into patch 
parameters that are beyond the range avaailable via the front panel.  
(I discovered this in the mid/late '80s when doing custom software 
for the CZ-5000 and the Commodore 64.)

For example, with the CZ-5000 sequencer, you can get shorter notes 
than you can via the user interface.  (I'm not sure if I have my 
documentation from the 1980s.)

It may be that the lack of batteries causes bogus data to be entered 
when you power up the CZ-101.  When you use the user interface to 
scroll down to a value within the acceptable range, the CZ will not 
let you scroll back up beyond the range from the user interface.

Try this:  

1.  Power up the CZ-101
2.  Find a patch (with bogus data) you like.
3.  Save the patch to a computer.
4.  Load the patch into the CZ-5000.
5.  Tell me if it sounds exactly the same as it did on the CZ-101.

If this works, you may have a psuedo-random CZ patch generator on 
your hands!!!!  ;-)

Hope this info helps.

PS:  I believe someone posted a method of initializing the patches on 
the CZ-101.  But be careful.  If you do this, you may no longer have 
a bogus patch generator!  ;-)
