2.3 MULTIPLE MIDI CONTROLLERS

It should be normally possible to combine SysEx commands from more than one MIDI controller. However, the 1788A-R does not have facilities for merging. You’ll probably need a commercially available MIDI merging box to receive the MIDI Outs from the multiple controllers and pass them to the 1788A-R(s).

2.4 CLONING 1788A’s

Any 1788A can import the parameters and stored labels from another 1788A by cross- connecting their MIDI IN and MIDI OUT ports. This can be the easiest way to replace a defective unit in a bank (as long as the defective unit is not completely dead, naturally).

Synchronizing Procedure

1.Temporarily cross-connect the MIDI IN and OUT ports as shown in Figure 2-8.

2.Put both units in Local Control.

3.Program both units to the same MIDI Channel and Device numbers.

4.On the unit to be updated (the clone), press both Tone Buttons and the CH 6 Select button then release. This transmits a dump request to the other unit (original).

The original unit will begin sending it’s parametric and label data to the receiving unit. The sender will show a series of ten messages in the sender’s display window indicating the transfer of ten blocks of data. The first eight blocks contains the preamp’s mic channel labels of 128 characters, the next block contains the sixteen master unit labels of 128 characters each, and the last block contains the complete parametric map.

When the transfer is complete, the clone will update itself to the new parameters and the panel indicators will align accordingly. The updated unit is now a clone of the original and will power up with the updated settings.
