Audio
MIDI Setup
utility and disable some channels as shown in
Figure 3-4 on page 19; leave others enabled.

Repeat this for the other devices in the daisy chain so
that no two devices have the same channels enabled.
For example, if you daisy chain a Korg Triton and a Roland
JV-1080, set the Triton to use channels 1-8 and the JV-
1080 to use channels 9-16.

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.
