Casio CZ/ VZ/ FZ - Pro Series

Using a 1990s era parallel port MOTU 8x8 midi router (port 8 in and port 8 out) connected to my CZ-3000, one and only one instance of midi-ox, and an XP SP3 PC (approc 6-7 years old), I successfully transmitted your first sysex bank (A) to the CZ and simultaneously received the acknowledgements from the CZ (F0 44 00 00 70 30 F7) on the first try. 

This is both good and bad.
GOOD:
--The patches work.
--This confirms that midi-ox can be used to send previously stored CZ banks in sysex form to the CZ. 

BAD:
My test doesn't help diagnose your problem.


Test number 2:
I disconnected the midi out cable from the CZ so that midi-ox would not receive the ack. I transmitted your second bank (B).

Result:
Midi-ox hung, waiting for an acknowledgement.

I then reconnected the midi out and retransmitted the second set of patches. It was as successful as the first test.

This is useful information. It tells us midi-ox needs the roundtrip midi connection.

Again, this was done with one instance of midi-ox. When I read the post that someone said you needed two, it struck me as odd and didn't square with my admittedly limited understanding of midi-ox. I reserved judgement and consciously chose not to comment until I had a chance to do an actual test. (I generally like to run tests if I have the time to confirm that I am not giving erroneous advice. Also, I usually learn stuff that I can use by running the tests.)

I am at a loss, though, as to how to pose further diagnostic questions so that you can be successful.  Maybe after dinner I will write up the steps I took. I fully expect that you already tried what I did, but as long as I have the CZ hooked up I might as well document the steps.
