New with V2.0: Parameter copy
It is now possible to copy settings to an accessory (AEC-PM2) and to copy them back to other MZ3. For this, remove the
front panel of the MZ3, insert AEC-PM2 in the designated plug. Connect OPA-S and copy parameter from MZ3 to AEC-PM2
by setting OP06 to 1.
AEC-PM2 "Data" LED is ON for 5 seconds after successful parameter copy and OP06 is set to 0. If the parameter copy
failed the LED blinks for 5 seconds and OP06 is set to 7.
Copy parameter from AEC-PM2 to MZ3 simply by pressing the "Copy" button on the AEC-PM2. AEC-PM2 "Data" LED is ON
for 5 seconds after successful parameter copy. If the parameter copy failed the LED blinks for 5 seconds.
