Latch Trim
In Latch Trim mode, Volume and Send level
Trim faders are disengaged from the main auto-
mation playlist and follow any existing Trim au-
tomation. When a Trim fader is touched, writ-
ing of Trim automation begins. Writing of Trim
automation continues until playback stops, or
until you punch out of writing automation.
When this mode is enabled, non-trimmable
controls (all controls other than track volume
and send level) behave as if they are in regular
Latch mode—they follow the previously written
automation until touched. When they are
touched, their absolute positions are written un-
til playback is stopped.
Touch/Latch Trim
In Touch/Latch Trim mode, Volume and Send
level faders are disengaged from the main auto-
mation playlist and follow any existing Trim au-
tomation. The main Volume Trim fader follows
Touch Trim behavior, and Send level Trim fad-
ers follow Latch Trim behavior.
Write Trim
In Write Trim mode, as soon as playback begins,
writing of Trim automation begins for Volume
and Send levels, and continues until playback
stops, or until you punch out of writing automa-
tion.
When Write Trim mode is enabled, non-trim-
mable controls (all controls other than track vol-
ume and send level) are not in Write mode, but
behave as if they are in regular Touch mode (no
automation is written unless a control is
touched). This is to prevent the controls from
overwriting all of their automation data on ev-
ery pass in Write Trim mode.
Automation Preferences
Pro Tools gives you several options for control-
ling the writing and playback of automation
data.
To display Automation preferences:
„
Choose Setup > Preferences and click Mixing.
The “After Write Pass, Switch To” prefer-
ence affects Write Trim mode. After an au-
tomation pass in Write/Trim mode, tracks
automatically switch to the Trim mode ver-
sion of the setting specified by this prefer-
ence.
