Casio CZ/ VZ/ FZ - Pro Series

I just pulled out The MIDI System Exclusive Book which does indeed 
have a published version of the CZ-1 sysex manual I have. (Somewhere 
in cyberspace there is a PDF of this

Here's the logic of the CZ commands
0x10 Send Request 1 (CZ-101 format)
0x11 Send Request 2 (CZ-1 format)
0x12 Send Request 3 (CZ-1 Operation Memory)
0x14 Send Request 2 (CZ-5000 Sequencer Data)
0x19 Send Request 2 (CZ-101 Effect Data)

0x20 Receive Request 1 (CZ-101 format)
0x21 Receive Request 2 (CZ-1 format)
0x22 Receive Request 3 (CZ-1 Operation Memory)
0x24 Receive Request 2 (CZ-5000 Sequencer Data)

0x30 Ready
0x31 Continue
0x32 Block End

I believe 0x40 - 0x59 are on the site you provided the link for.
I have handwritten notes that 0x42 is Tone Mix on some CZs. 0x53 is 
Split Point on the CZ-1. (Isn't that on the linked site?) 

I see nothing higher than 0x59.

If The Sysex Book is right, RZ-1 owners can use sysex to send and 
receive sample data and rhytm data (for those who don't want to use 
tape, I guess). Instead of F0 44 00 00 . . . use the sub ID 01 thus: 
F0 44 01 00 . . . . The command bytes are as follows:

0x10 Send Request 1 (RZ-1 Sample Data)
0x14 Send request 2 (RZ-1 Rhythm Data)

0x20 Receive Request 1 (RZ-1 Sample Data)
0x24 Receive Request 2 (RZ-1 Rhythm Data)

Of course, the RZ-1 User Manual doesn't include this info, but it 
just might work. If any RZ-1 owners give it a try, please post their 
results. Also, my guess is that the 0x14 Send Request and the 0x24 
Receive Request might also work on the SZ-1, just as it does on the 
CZ-5000. Any SZ-1 owvers out there?

BTW, for those units with the MT interface, years ago, I tested the 
use of a PC (wav file) with a CZ-5000. It worked, but I figured why 
bother; sysex is easier.

Anyone who wants to use Midi-Ox or any other software can test other 
command values, but I'd be surprised if there were any undocumented 
commands. Would be nice, though if there were a hidden/diagnostic 
dimension accessible via a special sub ID, but I doubt if the sysex 
code has any such thing. 

Has anyone here deciphered the ROM/operating system? If so, I'd look 
to see if there is any testing/handling of sub IDs. 

Anyhow, hope the above breakdown helps.
