Setting The Midi Channel - Behringer MODEL D Quick Start Manual

44 MODEL D
MODEL D Eurorack Installation
The MODEL D synthesizer can be removed from its factory
chassis and installed into a standard Eurorack chassis
(not supplied). The module width is 70HP.
We recommend that this procedure is undertaken only by
experienced service technicians, to prevent personal injury,
or damage to the unit.
The Eurorack case will need its own suitable power supply
unit to power the MODEL D synthesizer.
A 10-pin connector on the rear of the main PCB of the
MODEL D allows the +12 VDC power supply connection
to be made. A 10-pin to 16-pin adapter ribbon cable is
supplied to connect to your power supply.
Before proceeding, make sure that your
power supply is capable of supplying
+12 VDC, 1 Amp.
Make sure that the connections using the
supplied adapter cable will supply the ground
and power to the correct pins of X23.
Procedure
Follow all steps in the order in which they are presented.
1. Disconnect the power cord and all other
connections to the MODEL D.
2. Undo the 8 screws on the top panel as shown.
There is no need to undo any other screws.

9. Securely install the MODEL D Synthesizer into your
Eurorack, using 8 screws in the front panel.
10. Perform a full test and safety test before using
the MODEL D.
11. The 3.5 mm MAIN OUT connector on the top panel
is used instead of the ¼" rear outputs which are no
longer present.

Setting the MIDI Channel

Once installed in a Eurorack, the MIDI channel number is
automatically set to channel 1 (as the MIDI switches are
no longer present.)
The MIDI channel can be changed using MIDI OX or
a similar MIDI utility on your computer to send MIDI
SysEx commands directly to the MODEL D via the
USB MIDI connection. Here is a brief guide to the
procedure (see the MIDI SysEx pages in this manual for
the actual SysEx codes sent to the MODEL D):
1. Disable the MIDI Channel Switches by sending
the appropriate SysEx command.
2. Change the MIDI Channel by sending
the appropriate SysEx command.
