To monitor and mix audio from an Instrument plug-
in with multiple audio outputs:
1 Use an existing or create a new Instrument
track.
2 Choose View > Mix Window > Instruments to
show the MIDI controls of the Instrument track.
3 Select a multi-output instrument plug-in from
the first Insert selector on the Instrument track
(such as Transfuser).
4 The virtual MIDI node (port) for the instru-
ment plug-in should be automatically selected
for the Instrument track’s MIDI Output. If not,
select the MIDI channel and corresponding port
for the instrument plug-in.
5 In the plug-in window, assign the individual
audio outputs of the plug-in.
6 Create an Auxiliary Input track for each out-
put of the plug-in. Make sure the channel for-
mat of the Auxiliary Inputs corresponds to the
channel format of the plug-in outputs (mono,
stereo, or multichannel).
7 Set the inputs of the Auxiliary Input tracks to
receive the individual outputs of the plug-in.
8 Assign the outputs of the Auxiliary Input
tracks to the appropriate path or paths for
monitoring.
9 Adjust the Auxiliary Input faders to mix the
individual outputs of the plug-in.
Creating a Submix
A submix is created by routing multiple audio
sources to a common bus or output path. This
“submixes” the sources to a single path that can
be returned to an Auxiliary Input, where the
submix can be processed with plug-ins or exter-
nal effects processors.
Audio is routed to a submix by assigning any
combination of sends and track output to avail-
able bus or output paths.

Auxiliary Input tracks
When routing mono signals with internal
mix busses, be sure to use mono busses
rather than splitting stereo busses. Since
Pro Tools keeps stereo busses phase aligned,
splitting stereo busses can result in inaccu-
rate delay compensation.
