The Quantize window can apply Grid Quantize
when a specific rhythmic value is selected in the
Quantize Grid pop-up menu. When a groove
template is selected in the Quantize pop-up

What to Quantize
The What to Quantize settings determine what
aspects of any selected MIDI notes are quan-
tized: Note Ons (attacks), Note Offs (releases), or
both. You can also select whether to quantize
audio regions or Elastic Audio events. Depend-
ing on what type of track material is selected,
not all options will be available. If only MIDI is
selected, the Audio Regions and Elastic Audio
Events options are unavailable. If only audio is
selected, the Note On, Note Off, and Preserve Note
Duration options are not available.
Note On When selected, MIDI note start points
are quantized.
Note Off When selected, MIDI note end points
are quantized.
Preserve Note Duration When selected, MIDI
note durations are preserved.
When deselected with the Note On option se-
lected, note end points are not moved.
When deselected with the Note Off option se-
lected, note start points are not moved.
If the options for both Note On and Note Off are
selected, the Preserve Note Durations option is
unavailable.
The following figure shows how MIDI notes are
adjusted by the different What To Quantize op-
tions.
Audio Regions When selected in the What to
Quantize pop-up menu, Quantize is applied to
region start times (or sync points if present) for
selected audio regions. MIDI regions are not af-
fected. Typically, you will only want to apply
quantization to sliced audio regions or region
groups (such as imported REX files or regions
created using the Separate Regions at Transients
command or Beat Detective). Quantization can
be applied to mixed selections of MIDI notes
and audio regions.
Elastic Audio Events When selected in the What
to Quantize pop-up menu, Quantize is applied
to detected transient events within the Edit se-
lection on Elastic Audio-enabled tracks. Quanti-
zation can be applied to mixed selections of
