Remark:
The MIDI Controllers 28, 29 and 30 are translated inside the MAQ into Program-Change-
Events on the MIDI Channels of the 3 rows and transmitted at the MIDI out. Thus the sounds
of the expanders connected to MAQ out can be programmed.

Of course you may select the sounds at the control panel of the expander or using other
equipment sending Program-Change. In the last case the Program-Change data and the
MAQ data must be merged using a MIDI merger (e.g. Doepfer MMR4/4).

APPENDIX B: Display of MIDI-Errors

In case of a MIDI error the MAQ shows an error code in the display. You may continue by
pressing the Start/Stop button. But as the reason is normally a grave error you should store
the actual sequence if required and turn the MAQ off and on again.

The first letter for MIDI error codes is „

“. This letter was chosen as it does not occur during

the normal operation.

The following displays may appear:

I O: MIDI buffer overflow

Incoming MIDI data may be lost. This error occurs if the incoming MIDI data cannot be
processed by the MAQ. Reduce MIDI data rate and transmit to the MAQ only the data
required (i.e. MIDI Clock/Start/Stop for externa Sync, note on/off for transpose or remote
control events). You may use MIDI data filters or a MIDI output (e.g. computer) that delivers
only the data required by the MAQ.

HI oder

TI: Sys-Ex-Error

When receiving a SysEx-Dumps an error happened. Turn the MAQ off and on and try again.
The reason may be that the waiting time between two dumps was too short. The MAQ
requires about 10 seconds after a complete dump to store the data in its EEPROM. During
this time no dump must be sent to the MAQ.
