aries that do not touch or overlap other re-

Nondestructive Audio Editing
When editing an audio track’s playlist in
Pro Tools, you’re not actually cutting and
moving pieces of sound as you would if
you were cutting and splicing analog tape.
Instead, Pro Tools creates a map of the
audio file on your hard disk, which de-
scribes the order in which to play the track
portions.
When trimming audio regions with the
Trimmer tool, or when editing the place-
ment or order of regions within a track, use
multiple playlists to easily return to a
track’s previous state. See “Playlists” on
page 141 for details.
Audio Regions and Automation
Data
Automation data for audio resides in tracks
and not regions. This means that when you
drag an audio region from the Audio Re-
gions List to a new track, no automation
data is placed in the track. However, if you
drag an audio region from an existing track
(that contains automation data) to another
track, the automation from the source
track is placed in the destination track.
MIDI Regions and MIDI
Data
The two most common Display Formats
you’ll use for MIDI tracks are Notes and Re-
gions. Use Notes view for inserting and ed-
iting individual MIDI notes, and for work-
ing with and affecting groups of notes.
When you need to experiment with the ar-
rangement of regions, or define new ones,
use Regions view.
MIDI Notes Display
When a MIDI track’s Display Format is set
to Notes, MIDI notes are displayed in a “pi-
ano roll” format. Each note is displayed as a
small rectangle with its vertical placement
indicating pitch and its horizontal place-
ment indicating location.
To the left of the MIDI track’s playlist is a
vertical mini-keyboard, complete with oc-
tave numbering, for pitch reference. You
can Command-click (Macintosh) or Con-
trol-click (Windows) the mini-keyboard to
