Chapter 7: I/O Setup 121
Pro Tools Versions and Session
Interchange
When exchanging a session between systems with
different versions of Pro Tools software (such as
your Pro Tools 10.0 system and a colleague’s
Pro Tools 7.x system), you can use the following
to maintain paths and signal routing.
Pro Tools 8.1 and Higher
When exchanging sessions among systems run-
ning Pro Tools 8.1 or higher, it is generally recom-
mended that the
Sessions Overwrite Current I/O
Setup When Opened
option be disabled. This
maintains any system IO settings when opening a
session from another system (see “Sessions Over-
write Current I/O Setup When Opened” on
page 100).
Pro Tools 8.0.x and Lower
When exchanging sessions with systems running
lower versions of Pro Tools, it is generally recom-
mended that the
Sessions Overwrite Current I/O
Setup When Opened
option be enabled (see “Ses-
sions Overwrite Current I/O Setup When Opened”
on page 100). In this case, any custom settings
saved with the session that do not match your sys-
tem may need to be reconfigured manually in the
I/O Setup to match your current studio setup.
Opening Older Sessions in Pro Tools 8.1 and
Higher
When opening sessions created in Pro Tools 8.0.x
and lower in Pro Tools 8.1 or higher, output paths
from the legacy session are re-created as output
buses. If the
Sessions Overwrite Current I/O Setup
When Opened
option is enabled, the output buses
are mapped to session output paths.
Path Order and Overlapping Output Paths
When exchanging sessions between Pro Tools 8.1
or higher and Pro Tools 8.0.x and lower, output
paths and sub-paths are changed as follows, de-
pending on the order in which they appear in the
I/O Setups.
 If a session created in Pro Tools 8.1 or higher
contains overlapping paths with a larger path cre-
ated above smaller paths in the I/O Setup, the
smaller paths are converted to sub-paths of the
larger path when the session is opened in Pro Tools
8.0.x and lower.
 If a session created in Pro Tools 8.1 or higher
contains overlapping paths where a smaller path
appears above a larger path in the I/O Setup, the
larger path will be made inactive when the session
is opened in Pro Tools 8.0.x and lower.
If you created a backup of your I/O settings,
you can import settings after opening the ses-
sion (see “Importing I/O Settings” on
page 119).
If your hardware configuration has changed,
you may need to manually reconfigure output
assignments in the Grid on the Output page of
the IO Setup. See “Assigning Paths to Hard-
ware I/O” on page 113.
