Figure 2-3: Connecting a MIDI device to your MOTU MIDI interface. If
you are connecting a sound module or other device that does not
need to transmit MIDI data, you only need to make connection A
shown above. Conversely, if the device is a MIDI controller such as a
drum pad or guitar controller, you only need to make Connection B.
One-way MIDI connections
MIDI devices that do not receive MIDI data, such
as a dedicated keyboard controller, guitar
controller, or drum pad, only need Connection B
shown in Figure 2-3. Similarly, devices that never
send data, such as a sound module, only need
Connection A. However, if you plan to use editor/
librarian software with the sound module, or if you
need to get system exclusive bulk dumps from it,
make both connections. In general, make both
connections for any device that needs to both send
and receive MIDI data.

MOTU MIDI interfaces do not require that
you use the same numbered MIDI IN and MIDI
OUT for each device, but experience shows that
your system will be easier to work with if you do.
Connecting additional gear with MIDI THRUs
If you use up all of the MIDI OUTs on your MOTU
MIDI interface, and you still have more gear to
connect, run a MIDI cable from the MIDI THRU
of a device already connected to the interface to the
MIDI IN on the additional device as shown below
in Figure 2-4. The two devices then share the same
MIDI OUT port on the MIDI interface. This means
that they share the same set of 16 MIDI channels,
so try to do this with devices that receive on only
one MIDI channel (such as effects modules) so
their receive channels don’t conflict with one
another.
