4 If desired, select the Use Subframes op-
tion for greater accuracy.
5 Click OK. The material is shifted back or
forward by the specified amount.
If a portion of a region was selected, new re-
gions are created from the selection and
from any material outside of the selection.
The Shift command works the same regard-
less of the Edit mode. Adjacent regions are
overlapped in Shuffle mode, the Spot dia-
log does not appear when in Spot mode,
and shifted material does not snap to the
Grid when in Grid mode.
Quantizing Regions
The Quantize Regions command allows
you to adjust the placement of selected
audio and MIDI regions so that their start
points (or sync points, if they contain one)
precisely align to the nearest Grid bound-
ary, which can be based on frames, bar and
beat values, minutes or seconds, or a num-
ber of samples.
To quantize one or more regions:
1 Configure the Grid value as desired. For
details, see “Defining the Grid Value” on
page 186.
2 With the Grabber or Selector, select the
region or regions to be quantized.
3 Choose Edit > Quantize Regions. Region
start times (or sync points) are aligned to
the boundaries for the defined Grid.
For MIDI regions, all data contained within
the regions (such as notes) are moved
equally, thereby retaining their rhythmic
relationships. To quantize individual MIDI
notes, use the Quantize command in the
MIDI menu (see “Quantize” on page 214).
Locking Regions
If you have a region or group of regions
that you want to permanently associate
with a particular location in a track (a beat,
SMPTE frame, or sample location), you can
lock it in place so it will not be accidentally
moved.
To lock a region:
1 With the Grabber, select the region or re-
gions to be locked.
2 Choose Edit > Lock Region/Unlock Re-
gion.
A small lock appears in the region, indicat-
ing it has been locked and cannot be
moved. If you attempt to perform edits
that would move a locked region, Pro Tools
alerts you.
In Shuffle mode, locked regions, and all re-
gions occurring after the locked region, are
not displaced when other neighboring re-
gions are moved. If there is not enough
room to place or duplicate a region in front
of a locked region, the insertion area is dis-
abled.
▲ Locking a region prevents it from being
moved only—operations such as recording
and automation editing still affect it.
