Casio CZ/ VZ/ FZ - Pro Series

I took a quick look as I have a number of projects I am working on 
just now. 

681 is the size of the VZ single voice sysex dump.
55,958 is the size of of the 64 VZ Voices + 64 Op-Mems sysex dump.

The *.vz files (sizes 43,073 and 43,974) look like sysex data 
without the sysex header and EOX bytes.  There is no value above 7F, 
and it looks like nibblized data for numbers in a low range.

I may have more time to look at the files later.

As for using the VZ editor from posted earlier, I could not make it 
work successfully on an XP with the VZ-8m.  I could transfer some 
data, but the software then produced an error.  I am not sure if 
that's because I used a VZ-8m or XP.  I may try it on a WIn98 system 
one of these days.

Thanks for posting the files.

Hmmmmmm. Just looked at card1.b and card2.b.  On my copies the 1st 
byte of each file has a CE instead of an F0.

I am not sure why.  Other than that they look like a 64 patch vc+op 
sysex dump on channel 1. In debug you can change the byte and resave 
the file as card1.syx.  I am not sure if you can do that with 
MidiOx. (Don't change data bytes this way because it will proably 
throw the checksum off.  If you really wanted to, you could change 
things around in a zero sum manner--if you change one number by 
adding 3, make sure you subtract 3 somewhere else in the data.)

For example:

. . . 05 00 02 00 02 00 00 00 03 00 . . .

. . . 08 00 01 00 02 00 00 00 01 00 . . .

Or, if you add 1 some place, you could reduce the check sum by 1.  
The checksum is the number in the data portion of the sysex command 
before the F7. (See previous post showing open, data, close format.)
