Casio CZ/ VZ/ FZ - Pro Series

 OK, quick answer-- only connect to the "MIDI IN" on the CZ/VZ when 
editing patches with an external software patch editor.
 This seems to plague all Casio CZ/VZ synths. I'm guessing, but there
is a MIDI handshake protocol implemented by the Casio, that seems to
slow MIDI transfers. You only need the MIDI out from the Casio when 
uploading patches from the synth. After uploading the patches, simply
disconnect the synth MIDI out. I have a MIDI patchbay and just push a 
button to disconnect. Works great! You only need to send to the synth
"MIDI IN" to edit/store patches on the Casio.
 Another flaw in the CZ3000/5000 to be aware of, is the patch you send
to these synths doesn't register to the edit buffer, even though it's 
there.(huh?) You will have to manually edit one of the parameters on 
the front panel for the patch to register in the edit buffer. (what?)
 What happens is the new patch you just sent to your CZ3000/5000 will
play, however the "Compare/Recall" LED is not lit. Therefore when you 
try to save the newly edited patch, you will not be able to do so,
until the "Compare/Recall" LED is lit. Simply manually edit on the 
front panel by selecting "Octave" (or any parameter), and press the 
value up then down. This will light the "Compare/Recall" LED so the 
CZ3000/5000 can save the patch to the user memory. A pain but it
works. This is not necessary on the CZ1/101/1000/230S. And is not an 
issue if you are sending a MIDI sysex bank of 16 patches.
