Reserve Voices for Preview in Context
(Pro Tools HD Only)
Preview in context (previewing audio files in Digi-
Base during session playback) uses disk voices for
playback. The number of voices required depends
on the channel width of the selected Audition
Paths on the Output page of the I/O Setup window.
For example, if a stereo audition path selected in
the I/O Setup requires 2 voices for preview in con-
text, whereas a 5.1 audition path requires 6 voices.
If one or more voices are not available for preview
in context because they are in use by disk tracks (or
routing for RTAS processing), the Preview button
in DigiBase browsers will be unavailable during
session playback.
Pro Tools provides an option to reserve voices for
preview in context. The number of reserved voices
is determined by the channel width of the selected
Audition Paths in the I/O Setup. Voices reserved
for preview in context are unavailable for disk
tracks.
To reserve for voices for preview in context:
1 Choose Setup > Preferences.
2 Select the Operation tab.
3 Enable the Reserve Voices For Preview In
Context
option.
4 Click OK to close the Preferences dialog.
Linking and Relinking Files
A Pro Tools session is made up of references, or
links, to audio files and other session media. Audio
and video files must be stored on suitable Perfor-
mance volumes and be properly linked in order to
be playable in the session.
The following types of files are not playable:
Transfer Files Files that are stored on volumes not
suitable for playback, such as network volumes or
CD-ROMs.
Missing Files Files that cannot be found where the
session expects them, either because they have
been moved, or because they are stored on vol-
umes that are not currently mounted (offline vol-
umes).
The process of reacquiring missing files is referred
to as relinking. Relinking can involve certain sub-
tasks, depending on the situation.
• Transfer files must first be copied to a suitable
Performance volume. The session is then re-
linked to the copies on the Performance volumes
instead of the original Transfer files.
• Volumes may be searched for missing files and,
when the files are found, Pro Tools relinks the
session to the file's new location.
• Files that reside on offline volumes must first
have their volumes mounted (brought online)
before they can be relinked.
Deselect the Spacebar Toggles File Preview
option in the Browser menu to start and stop
session playback with the Spacebar without
previewing in the DigiBase browser. Use
Command+P (Mac) or Control+P (Win-
dows) to start and stop preview in the front-
most DigiBase browser during session play-
back.
Catalogs have unique linking characteristics.
