Casio CZ/ VZ/ FZ - Pro Series

I have acquired a Knobby midi controller, and want to use it to change 
the attack, decay, etc parameters on the fly on my CZ-5000.  Where do I 
start in terms of the sysex specifics for this machine?  I have manuals 
somewhere, but I don't think they go into the midi internals in great 
detail. 

Thanks for any help.

I'm not sure this work properly since afaik the sysex specifications of the CZ 
only allows full patches to be send and no single parameter changes...

There is a CZ Sysex manual in the files section of this list...

Summa is - as always - correct.

Changeable via sysex is only stuff like porta range, glide time, etc. The
handshake protocol even adds more complication.

Hi Hellmuth,

so nobody did it?
I've read some stuff about virtualizer (soundquest homepage).
And with this you should be able to control  the cz5000 realtime.
However my main goal is to use a Kenton controller (spin doctor).

Another question is should I always send a complete sysex for changing only one parameter?
Is there a way to send a patch change and affect only one parameter without avoid to change / reset the rest of the patch?
This could be a turnaround.

Will try....

My recollection is that patch parameter data is read into a sound area and the sounds are played from the sound area. Unless you modify the circuitry, I doubt you can change patch parameters on-the-fly.

You might be able to simulate parameter changing with successive note-ons using a technique I did with the Commodore-64 (circa late 1980s).

My program was an "Infinite Keysplit" routine that worked in mono mode as follows:
Basic operation:
1. Turn local off.
2. Route CZ-5000 midi out to computer (midi in).
3. Run software [custom software on C-64]*.
4. Route midi out (computer) to CZ-5000 (midi in).

*Software operation:
Basically, I had a table of patch changes for each incoming note. I tracked midi channel usage. With each new note-on, I sent a program change on an available channel, followed by a note-on command on that channel.

I am not sure if sending sysex data to the CZ will re-trigger or terminate notes currently on. If not, you could try my technique sending sysex data for each new note on instead of patch change data.

If the sysex does indeed re-trigger or terminate notes, then you could have a series of related patches to simulate change from note to note.

Software programability could be added. For example, the software could have an lfo to control the rate at which patches are changed and the lfo could be programmed to respond to an incoming CC.

I think somewhere on the Infobahn are schematics for one of the CZs (perhaps the CZ-1). There may also be some DIY CZ-101 mods. Perhaps it is possible to redesign the CZ to have realtime controls (other than the chorus). 

Of course, maybe by now, someone as come out with a new, improved CZ OS. Hmmmmm.

Hope this helps.
