from, its associated audio regions. (MIDI auto-
mation data always follows region editing, with
the exception of mute. See “MIDI Tracks” on
page 452 for more information.)
When you copy or cut audio data from a track
while it is in Waveform View, the underlying au-
tomation data is cut or copied with it.
If you paste audio data from other locations or
tracks into an edit playlist, you may change the
underlying automation data on the track.
When you trim regions using Edit > Trim, the
underlying automation data remains un-
changed.
Duplicating Tracks for Playlist Editing
The Duplicate Selected Track command pro-
vides a convenient way to make a working copy
of a track to experiment with routing, plug-ins,
and automation. This protects the original track
and its automation data from being edited or
overwritten.
To copy a track for automation:
1 Select the track and choose File > Duplicate
Track. Duplicate Track creates a complete copy
of the track, including all routing, plug-ins, and
automation.
2 Command-Control-click the Track Type icon,
or select that track and choose File > Make Se-
lected Tracks Inactive.
3 Edit automation on the duplicated track.
Automation Modes
Each track provides an Automation Mode Selec-
tor. Automation modes control how a track’s
automation data is written and played back.
Auto Off
Auto Off mode turns off automation for all au-
tomatable parameters:
•Volume
Pan
Mute
Send volume, pan, and mute
Plug-in controls
MIDI volume, pan, and mute
In Auto Off mode, automation data for these pa-
rameters is ignored during playback. All other
MIDI controller data is sent.
Auto Read
Auto Read mode plays the automation that was
previously written for a track.
Auto Write
Auto Write mode writes automation from the
time playback starts to the time it stops, erasing
any previously written automation for the dura-
tion of the automation pass.
After an automation pass, Pro Tools automati-
cally switches from Auto Write mode to Auto
Touch mode. This prevents you from acciden-
tally overwriting automation data on later play-
back. On TDM systems, you can turn off this be-
havior and remain in Auto Write mode. See
“Write Switches To Touch After Pass” on
page 61 for details.
For more information, see “Editing Auto-
mation” on page 467.
