CONNECTING MIDI GEAR
Connect each MIDI device’s MIDI IN jack to a MIDI OUT
jack on your MOTU MIDI interface as shown by
Connection A below. Conversely, connect the MIDI OUT
jack on the MIDI device to one of the MIDI IN jacks on
your MOTU MIDI interface as shown by Connection B.
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
