Casio CZ/ VZ/ FZ - Pro Series

Hi

I've a cz 1000 and found tools, patches and this group on the net. 
Now I would like to store and load patches or banks via midi on my 
pc. I tried with a patch editing software (cz sysex editor). PC and 
cz are linked by midi (both directions). midi button is pushed on cz. 
Testing connection was positive (could send/receive midi data with 
same connections and other software.

Neither importing nor exporting patches does show any actions on the 
pc or cz. I'm not sure if I do it the right way Since the manual does 
not describe this transaction. Has anyone experience or an idea if 
there's needed special settings or... ???

Tips would be appreciated
