Casio CZ/ VZ/ FZ - Pro Series

It sounds like you have a nagging problem that simply should be 
there. I have never had a CZ-1000, but it should work the same as 
other CZs. You probably tried all of this, but perhaps these 
diagnostic steps will help locate the problem.


1. Do you have a complete midi loop? In other words, is the MIDI OUT 
of the CZ going to the MIDI IN of your computer and is the MIDI IN of 
the CZ going to the MIDI OUT of the computer?

2. Is the CZ receiving commands?
Simple test: On channel 1 (N=0) send a 2-byte program change command.
eg [in hex] C0 09
Does the path change? 
If not, try this with other gear to see if the data is going out 
successfully.
From what you wrote, it seems like the CZ is indeed responding to 
program chgange messages, but it doesn't hurt to verify.

3. Is the computer receiving midi data?
Simple test: Play some notes and see if the software (Boomes, midi-
ox, sequencer)captures it.
Again from what you say, this does not seem to be a problem.

(At this point, if you have a sequencer, you could play the note data 
captured back to the CZ to make sure that works. But let's assume 
that it does.)

4. Will the CZ respond to simple sysex commands?
Simple test: Send tone mix on command.
a. Set basic CZ channel to 1.
b. Manually turn tone mix off.
c. Send command:   F0 44 00 00 70 42 49 F7
Did mix turn on? I really hope so!!
(You could also try the Transpose command.)

If you had success with step 4, try the send request. I am not sure 
if the memory protect switch prevents sysex data transfer, but you 
could ttry turning it off--just so long as you don't accidentally 
wipe out important data.

Remember that N goes from 0 to F (hex) for channels 1 to 16. (N = 
channel number minus 1.) So, if the basic channel is 1, the request 
for preset tone 3 should be: F0 44 00 00 70 10 02 70 31 F7.

I would try this both with the final F7 and without it, turning off 
the CZ after each attempt. I seem to recall (at least on the CZ-
5000), the CZ will wait and wait for a final F7. If I am remembering 
correctly, this will prevent the CZ from seeing other incoming sysex.

I have been meaning to pull out my CZ-5000 from mothballs, so if 
these steps don't work, let me know and I will do some hands on 
testing.

BTW, do you have a midi sequencer? I seem to recall that years ago I 
created a midi file (or two) to send patch data to the CZ, play some 
notes so you can hear the patch, and then send another set of patch 
data.  If you have a sequencer [doesn't midi-ox have a simple midibar 
program to play midi files?) maybe you could try that. I will look in 
the files section.

Apologies if you tried all of this before, but on the chance that it 
would help, I thought I'd try.
