Chapter 36: Region Loops and Groups 747
A region group is separated when you do any of
the following:
• Insert a track within a multitrack region
group.
• Move a track that is part of a multitrack region
group so that it is no longer adjacent with the
other tracks of the region group.
• Hide a track that is part of a multitrack region
group.
• Delete a track that is part of a multitrack re-
gion group.
• Change the tempo of a mixed sample-based
and tick-based region group.
• Record into a region group.
• Change playlists on a track that is part of a
multitrack region group.
• Change to Playlists view.
• Apply manual warping in Warp view.
There may be situations where you want sepa-
rated region groups. For example, if you use the
same accompaniment on verses one and two of
a song, you can group the parts of verse one and
copy them as a region group for verse two, but
still have a continuous vocal track in the middle
of those region groups.
Region Groups on Tick-Based
Tracks
When changing tempos, region groups on tick-
based tracks adjust their length by adjusting the
position of all enclosed regions accordingly.
This can be useful for arranging rhythmic mate-
rial and for playing back region groups imported
from REX and ACID files.
Changing Region Group Timebase
The timebase format of a region group can be
changed by:
• Changing the track’s timebase.
– or –
• Dragging the region group to a track with a
different timebase.
Changing the timebase creates a copy of the
original region group. Both region groups (the
original and the copy) appear in the Region List,
but they have different timebases.
If you want to delete a track and keep the
region group intact, first ungroup the region
group, then delete track, and then Regroup
the region group. The region group will be
recreated intact, but without the deleted
track.
