Casio CZ/VZ Files... part of CZsynth

Since you are getting a "LOAD ERROR" message, I am inclined to agree that it is  buffer overflow error (data coming too fast).  Either that or maybe the data is corrupt. If the data you are using posted somewhere?  If so, I can try it on a VZ-8m.

From around 2004, re: VZ error messages: 

*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.
---------------------------------------------------------------
To see the channel and size of data, you can use debug [PC].
