Pro Tools Reference Guide82
Factory I/O Settings Files
Pro Tools provides I/O Settings files for Stereo
and Surround mixing. These files provide ge-
neric main and sub-path definitions for either
mixing format.
Stereo Mix Settings File
The Stereo Mix preset consists of all possible ste-
reo and mono paths for your session.
Specifically, the Stereo Mix preset will create the
maximum number paths of each type, as deter-
mined by the available system’s I/O Setup and
hardware configuration.
Surround Mix Settings File (TDM Systems Only)
The Surround Mix provides additional, sur-
round-specific Output and Bus presets. See “Sur-
round Mix Settings Files” on page 509 for more
information.
About Direct Outputs Mode
Direct Outputs mode, as found in older versions
of Pro Tools, has been replaced by the default
mono sub-paths available through all valid I/O
in the I/O Setup dialog.
The Default switch creates main Output paths
with appropriate mono sub-paths. These sub-
paths provide discrete monophonic routing.
When a session is opened that was saved in Di-
rect Outputs mode, Pro Tools maps all the out-
put assignments to equivalent mono sub-paths
(as available). See “Hardware Setup and Session
Transfer” on page 79 for more information on
remapping.
To convert a session so that it emulates Direct
Outs mode, use the Auto Assign Ascending Out-
puts feature, as follows:
To auto assign track outputs for Direct Out:
1 Make sure that all tracks you want to assign
are visible (hidden tracks will not be affected).
2 Select the tracks you want to assign by Shift-
clicking their track names.
3 Control-Alt-click (Windows) or Command-
Option-click (Macintosh) the Output Selector of
the leftmost track and assign it to the sub-path
for Output #1. All visible tracks will be auto-as-
signed to unique mono sub-path outputs in as-
cending order.
I/O Setup Options
Pro Tools systems have additional I/O Setup fea-
tures. These include default signal routing for
metering and auditioning, and default track lay-
out for multichannel mix formats.
Meter Path Selector
(ProControl Only)
The Meter Path Selector determines the path
displayed across the ProControl Output meters.
See the latest ProControl documentation for
more details.
Audition Path
The Audition path is the output path through
which files and regions are previewed (listened
to) in the Regions List.
Using the “Stereo Mix” preset has the same
effect as clicking Default for every individ-
ual tab in I/O Settings. See “Creating and
Editing Paths” on page 73 for details.
