perform a full reset the user memory (static RAM or flash EEPROM*) is first cleared and 
immediately after the whole content of the EPROM is stored inside. All this procedure is a 
part of the synth OS, i don't think you can disable it with a MIDI sysex code.... 

From the AN200 User Guide, Factory Reset:

1) Turn the power off.

2) Simultaneously hold down the [SHOW VALUE], [PATTERN] and [EXIT] buttons, and turn on 
the power again.
