Chapter 5: Advanced Automation Features 33
Trim Mode
You can adjust (or trim) existing track volume
and send level automation data in real time.
Pan, mute and plug-in automation cannot be
trimmed in this manner. Trim mode works in
combination with the other Automation modes
(Read, Touch, Latch, Touch/Latch, and Write)
and is useful when you want to preserve all of
your volume automation moves, but need to
make levels a bit louder or softer to balance a
mix.
When writing automation in Trim mode, fader
moves write relative rather than absolute values.
The existing automation data is changed by the
amount of increase or decrease (or the delta
value) indicated by the faders.
When Trim mode is enabled, non-trimmable
controls behave in the same manner as in the
standard Automation modes, with the excep-
tion of Write/Trim mode, where non-trimmable
controls operate as in Touch mode.
Trim Automation Modes
When a track is in a Trim automation mode (ex-
cept for Trim Off) its main Volume faders and all
Send level faders are displayed in yellow. When
trimming, a track’s Volume indicator or Send
Level indicator shows the delta value being writ-
ten rather than the absolute value.
Behavior of the Trim Automation modes also
depends on the Coalesce Trim Automation pref-
erence setting. See “Coalescing Trim Automa-
tion” on page 42.
Trim Off
Trim Off turns off reading and writing of all au-
tomation (main and trim) for a track. All auto-
mation moves are ignored during playback.
Trim faders are temporarily set to zero when a
track is set to Trim Off mode.
Depending on the Coalesce Trim Automation
preference setting, changing a track to Trim Off
can coalesce Trim automation on that track. See
“Coalescing Trim Automation” on page 42.
Automation can be switched from Trim Off to
another Automation mode during playback or
record.
Read Trim
In Read Trim mode, Volume and Send level
Trim faders are disengaged from the main auto-
mation playlist and follow any existing Trim au-
tomation. You can move a Trim fader during
playback to audition new trim values, but no au-
tomation is written. When the Trim fader is re-
leased, it returns to any previously written Trim
automation values.
If a track does not contain Trim automation,
you can move a Trim fader during playback to
audition new trim values, but no automation is
written. The Trim fader retains its position until
the track is removed from Trim mode, or if you
manually coalesce the Trim level.
When this mode is enabled, non-trimmable
controls (all controls other than track volume
and send level) behave as if they are in regular
Read mode—no automation data is written.
