ADA MP-1 Classic owner’s manual
SOFTWARE VERSION
The MP-1 CLASSIC displays the current installed software version during power-up. It is
three digit read-out (1.00) which is displayed just after the LED's flash in the power up
sequence.
SELF DlAGNOSTICS & ERROR CODES
The MP-1 CLASSIC's internal self-diagnostic functions automatically check the unit for
memory errors during power up. Additional checks are made when data is received in the
form of MIDI System Exclusive messages. When an error is detected during power up, one
or more error messages will be displayed. The following chart shows the error code that will
be displayed in the event of a problem. the cause of the problem and the appropriate action
for you to take.
Diagnostic status is also available via MIDI System Exclusive messages. For information on
MIDI diagnostics, please refer to the ADA SYSTEM EXCLUSIVE SPECIFICATION, which
may be ordered from your authorized dealer, or directly from ADA. Error codes occur very
rarely, if ever, and some are a direct result of external causes and do not cause permanent
damage. All the error codes listed below up to Err 2 are a result of memory locations being
corrupted, most likely because of voltage spikes or sags in the AC power line. Again, we
recommend using an AC power conditioner if this is a recurring problem. If the error
message does not show up after entering the data again, there is no damage to the unit. If
the error messages continue, contact the ADA Customer Service, you may need a new back-
up battery. Err 3 and Err 4 are an indication that the SYSEX file just sent to the unit's MIDI IN
jack is not in accordance with the ADA MIDI SYSEX specification. Neither Err 3 nor Err 4 is
an indication of a problem within the unit. Err 5 and Err 6 are indications that the memory
hardware has problems and should be replaced.
