Hardware Setup and Session
Transfer
Pro Tools sessions store the type and order of au-
dio interfaces connected and active when the
session was last saved.
Unavailable I/O
When opening a session, Pro Tools checks to see
if the hardware configuration has changed since
the session was last saved. If the current hard-
ware configuration differs from that saved in the
session, paths associated with the unavailable
I/O are made inactive.
Remapping
Remapping occurs when a session’s original
I/O Setup does not match that of the current
system and session paths are remapped to cur-
rent hardware.
Systems of equivalent I/O capability are
remapped directly. For example, a session
tracked to a Pro Tools|HD system through two
192 I/O audio interfaces would include 32 input
paths spread across the two 16-channel inter-
faces. The session is taken to a second Pro Tools
system that has a 96 I/O audio interface (a 16-
channel I/O unit) and a 1622 I/O (with its 16 an-
alog inputs) connected to its Legacy Port. When
the session is first opened on the second system,
Pro Tools will map the 32 input paths to the in-
puts 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 Last Saved 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 Last Saved Setup button displays the
audio interfaces used in the original session.
This temporary display lets you check the last
saved I/O configuration for reference while con-
figuring 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.
See “Active and Inactive Paths” on page 54
for more information.
To redefine the paths, see “Creating and
Editing Paths” on page 49.
