Casio CZ/ VZ/ FZ - Pro Series

First of all, thanks for all the replies. It's nice to see how active this group is.


The protect switch is off, and the keyboard is in MIDI mode on default settings.

The patches I'm trying came from the "CZ starter kit" you can find on eBay, or patches I've downloaded from this and the other CZ Yahoo group. I'm trying several different ones.

Previously I was using a $4.00 MIDI>USB cable from Amazon, which I later discovered does not support Sysex. I haven't seen any reports of the Hosa USM-422 I'm using now failing to transmit Sysex data. I suppose a defective cable could be possible, but I would think a defective cable should turn up more defects than just Sysex ability...

I'd like to recieve and back up my own patches first, but I'm also attempting to send SYX patches which will overwrite mine. (I don't mind as long as I can get this working) The procedure I'm using is this-


Receiving
In MIDI-OX, I select USB Audio Device (the only option) as MIDI IN, and for MIDI OUT, my options are USB Audio Device, USB Audio Device [2], MIDI Mapper, and Microsoft GS Wavetable SW Synth. I usually select USB Audio Device [2], though I get the same result with all of them. after tapping a few keys to see the key on/off messages in the monitor window, I open "View > Sysex" and in the command window I paste F0 44 00 00 70 10 20 70 31, which according to the tutorial I mentioned in the first post is the command to request the patch from internal memory 1. (A1) I've read about F7 being the proper byte to end a command with, and that the CZs ignore that byte? So I select "Command Window > Send/Receive sysex" the green light on the MIDI>USB cable flashes once, and a message pops up- "[Wait for completion] 0 Bytes Received" and just stays at 0. I've tried adding the F7 byte and still nothing happens.

Using Bome's SendSX, I will load F0 44 00 00 70 10 20 70 31 into the MIDI Out field, hit send and it says "Sys Ex was sent sucessfully". Nothing happens.

I've also tried omitting the last two bytes as per fulfil_objective's suggestion, and still nothing happens.



Sending
Using MIDI-OX, I will load a sysex patch in the command window and select "send". The green light on the cable flashes once, and nothing happens. 

Using Bome's SendSX, I will load a sysex patch into the MIDI Out field, and says "Sending line X of 8" (or "Sending line X of 128" depending on the patch) sending each line, the green light on the cable flsahing each time. A message tells me the patch was sucessfully sent, and nothing happens. The display on the CZ never changes and there are no new sounds.


Am I doing something wrong here?
