DAISY-CHAINING MIDI DEVICES
In general, daisy-chain MIDI devices (as shown in
Figure 3-4 on page 21) should be avoided because it is
more complicated to set up than connecting each device
directly to your MOTU interface.
If you have no choice but to daisy-chain, you need to
configure each device such that it doesn’t share any MIDI
channels with other devices in the chain. Otherwise, you’ll
hear several instruments play at once because data sent to
one unit is received by all the devices in the daisy chain
that are listening to that same MIDI channel. Refer to the
following Mac or Windows section that applies to you.
Configuring your Mac setup for daisy-chaining
1 Double-click on the first device in Audio MIDI Setup
and disable some channels, as shown in Figure 3-3 on
page 19; leave others enabled.
2 Repeat this for the other devices in the daisy chain so
that no two devices have the same channels enabled. For
example, set Device A to use channels 1-8 and Device B to
use channels 9-16.
3 Now go to the front panel of each MIDI instrument
itself and program it to respond to only the channels that
are enabled in Audio MIDI Setup. Refer to the
documentation for the device for details on this last step.
