Edit Playlists and Automation
Pro Tools handles audio regions and playl-
ists differently from MIDI regions and play-
lists.
Audio Tracks
On audio tracks, automation data resides
on a separate playlist from audio data and
regions. Each edit playlist on an audio track
shares the same automation data.
When you trim audio regions with the
Trim tool, the underlying automation data
remains unchanged.
MIDI Tracks
On MIDI tracks, all controller automation
data except for Mute data is contained in the
MIDI region that it was recorded in. Each
edit playlist on a MIDI track is separate,
and represents a distinct performance,
complete with controller automation.
When you trim MIDI regions with the Trim
tool, the controller automation data is
trimmed with the other MIDI data.
▲ Mute data is independent of the MIDI data
in a MIDI region. This allows you to mute play-
back of individual MIDI tracks in Pro Tools with-
out altering the controller data.
Multiple Edit Playlists and Audio
Tracks
All edit playlists on a single audio track
share the same automation data. When
you copy or cut audio data from a track
while it is in Waveform view, the underly-
ing automation data is cut or copied with
it. If you paste audio data from other loca-
tions or tracks into an edit playlist, you
may change the underlying automation
data on the track.
If you are using multiple edit playlists to as-
semble different versions of your audio
tracks, you can avoid problems with auto-
mation by editing and assembling the
audio tracks before applying automation to
them.
Automation Modes
Automation modes control how automa-
tion data is written and played back.
Auto Off
Auto Off mode turns off automation for all
automatable controls:
• Volume
• Pan
• Mute
• Send Volume, Pan, and Mute
• Plug-In parameters
• MIDI Volume
• MIDI Pan
• MIDI Mute
In Auto Off mode, automation data for
these parameters is ignored during play-
back. All other MIDI controller data is sent.
