Chapter 22: Editing Basics 433
Nondestructive Audio Editing
When editing an audio track’s playlist in
Pro Tools, you are not actually cutting and mov-
ing 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 describes the order in which to
play various portions of the audio.
When trimming audio regions with any of the
Trimmer tools, or when editing the placement
or order of regions within a track, you can use
multiple playlists to easily return to a track’s pre-
vious state. For more information, see “Playlists”
on page 529.
Audio Regions and Automation
Data
Automation data for audio resides in tracks and
not in the Region List. This means that when
you drag an audio region from the Region 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.
You can edit automation data by switching track
views or by revealing the automation lanes un-
der the track.
MIDI Regions and MIDI Data
The two most common Track Views you will use
for MIDI and Instrument tracks are Notes and
Regions:
‹
Use Regions view for arranging regions.
‹
Use Notes view for inserting and editing indi-
vidual MIDI notes, and for working with and af-
fecting groups of notes.
Regions View for MIDI and
Instrument Tracks
MIDI and Instrument tracks can be viewed as
Regions, which is similar to Waveform view for
audio tracks. While a track’s notes are visible in
Regions view, individual note editing is not
available in this view. Instead, all editing occurs
across a time range encompassing all track data,
including continuous controller events, pro-
gram changes, and System Exclusive events.
Use Regions view to define regions that repre-
sent song sections and clips, or to rearrange or
assemble track material.
In Regions view, the vertical zoom is automati-
cally scaled to fit the entire range of pitches of
MIDI notes on a track.
For more information on automation, see
Chapter 42, “Automation.”
For more information on setting Track
View, see “Track Views” on page 169.
To toggle the Track View between Notes
and Regions, click in the track you want to
toggle and press Start+Minus (Windows) or
Minus (Mac) on the alphanumeric
keyboard.
You can double-click a MIDI region to open
it in the MIDI Editor window. See
Chapter 30, “MIDI Editors.”
