The Shift command works the same regardless
of the Edit mode. For example, adjacent regions
are overlapped 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 to Grid
The Quantize to Grid command adjusts the
placement of selected audio and MIDI regions
so that their start points (or sync points, if
present) precisely align to the nearest Grid
boundary.
To quantize one or more regions:
1
Configure the Grid value (see “Defining the
Grid Value” on page 433).
2
With the Selector or Time Grabber tool, 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 Region > Quantize to Grid. Region
start times (or sync points) are aligned to the
nearest boundaries for the defined Grid.
For MIDI regions, only the regions are quantized
and all MIDI data contained within the regions
(such as notes) are moved equally, thereby re-
taining their rhythmic relationships. To quan-
tize individual MIDI notes, choose Event > MIDI
Grid/Groove Quantize (see “Grid/Groove Quan-
tize” on page 584).
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 can-
not be moved accidentally. Locked regions can-
not be moved or deleted.
To lock (or unlock) a region:
1
With the Time Grabber, select the region or re-
gions to lock (or unlock). The regions can reside
on multiple tracks.
2
Choose Region > Lock (or Region > Unlock).
When locked, a small lock appears in the region
and it cannot be moved or deleted. 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.
