Chapter 17: Working with Regions and Selections 279
The Shift command works the same regardless
of the Edit mode. Adjacent regions are over-
lapped in Shuffle mode, the Spot dialog 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 adjusts 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
boundary, 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. For details, see “De-
fining the Grid Value” on page 275.
2 With the Grabber or Selector, select the region
or regions you want to quantize. The regions
can be on multiple tracks. Only regions that are
entirely selected will be quantized.
3 Choose Edit > Quantize Regions. Region start
times (or sync points) are aligned to the bound-
aries 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 380).
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 sam-
ple 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 regions
to lock. The regions can even reside on multiple
tracks.
2 Choose Edit > Lock/Unlock Region.
A small lock appears in the region, indicating it
has been locked and cannot be moved. If you at-
tempt to perform edits that would move a
locked region, Pro Tools alerts you.
In Shuffle mode, locked regions, and all regions
occurring after the locked region, are not dis-
placed when other neighboring regions are
moved. If there is not enough room to place or
duplicate a region in front of a locked region,
the insertion area is disabled.
Locked audio region
Locking a region prevents it from being
moved or deleted only—operations such as
recording and automation editing still af-
fect it.
