As for the second error message, maybe this will help, though you seem to have third type of error message (Load Error: Check Message), so I am not sure. I couldn't find the "previous message about channel and data type matching." Maybe I had the error listed there. Casio CZ/ VZ/ FZ - Pro Series
*Here are the error messages I have been getting when sending VZ
sysex data to the VZ-8m. (See my previous message about channel and
data type matching.)
---------------------------------------------------------------
Message: --TRANS ERROR--- | CHECK SYSTEM!
Problem: Data channel <> VZ receive channel
Solution: Change VZ channel to match sysex file data.
Message: --MIDI ERROR--- | RECEIVE ERROR
Problem: Data type transmitted <> Data type expected
Solution: Select proper data type when loading data type into VZ.
