face (a 16-channel I/O unit) and a 1622 I/O
(with its 16 analog inputs) connected to its Leg-
acy Port. When the session is first opened on the
second system, Pro Tools will map the 32 input
paths to the inputs of the two interfaces.
When hardware is unavailable to a session being
opened, assignments can either be replaced us-
ing the remap option, or opened as Inactive.
Any tracks left assigned to an unavailable path
will not be audible. This can be beneficial, how-
ever, when you want to reassign tracks into your
system’s mix one at a time.
Show Original Setup and Show Current Setup
When a session is opened that contains path
definitions for unavailable I/O interfaces, the
I/O Setup dialog lists those paths in italics.
The Show Original Setup button displays the au-
dio interfaces used in the original session. This
temporary display lets you check the original
I/O configuration for reference while configur-
ing the session for your system.
Once a session has been opened with unavail-
able I/O retained, you can then reassign tracks
to available I/O paths.
I/O Settings Files
I/O Settings can be managed when transferring
sessions, and when developing I/O Setup con-
figurations over the course of multiple sessions
and projects.
Defaults, Settings Files, and Last
Used Settings for New Sessions
When creating new sessions, you can set the ses-
sion’s I/O Setup configuration using the follow-
ing options:
Default I/O Setups The Pro Tools Installer pro-
vides factory presets for stereo and surround I/O
Setups (surround mixing is only supported on
Pro Tools HD-series and MIX-series systems).
See “Factory I/O Settings Files” on page 82 for
more information.
Custom Presets You can store and recall custom
presets using the export and import features of
the I/O Setup dialog.
Last Used The most recent (or last used)
I/O Setup configuration is saved as a Last Used
settings file. See “Last Used I/O Settings” on
page 81 for more information.
Default I/O Settings at First Launch
The first time you create a session, you can
choose default Stereo Mix or Surround Mix set-
tings, depending on your system and installa-
tion choices. See “Factory I/O Settings Files” on
page 82.
See “Active and Inactive Paths” on page 78
for more information.
To redefine the paths, see “Creating and
Editing Paths” on page 73.
