DigiDesign Pro Tools 8.0 Reference Manual page 768

When changing tempo with region groups
on tick-based tracks, you may need to Un-
group, redo or create new fades, and then
Regroup in order to maintain the fades.
For information on working with fades and
crossfades in Pro Tools, see Chapter 26,
"Fades and Crossfades."
Importing and Exporting Region
Group Files
Pro Tools can export and import region groups
as region group files (.rgrp) to do any of the fol-
lowing:
• Separate region group metadata from audio
files to avoid unnecessary file copy opera-
tions when exporting audio region groups
composed from multiple source files
• Export MIDI data as part of a region group
• Create multitrack loops
Region group files store the following metadata:
• References to all audio files within the re-
gion group
• Region names and relative location in
tracks
• Embedded fades and crossfades
• Region group names and format (single or
multitrack)
• All MIDI data present in the region group
(such as notes, controllers, Sysex, and so
on)
• Track names
• Elastic Audio Warp markers and TCE factor
• Region timebase (samples or ticks)
• Sync points
• Loops
• Tempo map
