Chapter 42: Automation 909
Send Levels and Trim Mode
(Pro Tools HD Only)
You can set Pro Tools to exclude Send levels
from Trim mode, so that only the Main Volume
goes into Trim when a track is put into Trim
mode. This gives you more flexibility in setting
Send levels while in Trim mode.
1 To exclude Send levels from Trim mode:
1 Choose Setup > Preferences and click Mixing.
2 Under Automation, deselect Include Sends in
Trim Mode .
3 Click OK.
Smoothing
When you perform automation moves (includ-
ing Trim moves) with a continuous control,
Pro Tools records the move as a series of very
small steps, resulting in a staircase pattern with
many breakpoints. Smoothing intelligently re-
solves this staircase pattern into a single,
smooth ramp from one breakpoint to the next.
(Smoothing does not apply to switched controls
such as mutes or plug-in bypasses.) With
smoothing enabled, the resulting automation
data is often a more accurate representation of
actual automation moves.
Thinning
Thinning automatically reduces the overall
number of breakpoints in an automation playl-
ist (including Trim playlists) in order to improve
system performance. The amount of thinning
applied is determined by the Degree of Thinning
setting in the Automation Preferences page.
When using high amounts of thinning, the re-
sulting automation may differ noticeably from
the original automation moves. Thinning only
applies to audio tracks, and does not affect MIDI
tracks. For instructions, see “Thinning Automa-
tion” on page 925.
AutoMatch Time
AutoMatch Time is the amount of time it takes
for a fader to return (by ramping up or down) to
the level of automation still on the track as the
automation pass ends. This time value is set in
the Automation Preferences page (see “Automa-
tion Preferences” on page 908).
AutoMatch is automatically applied to all Touch
mode passes, and can be applied to Latch or
Write passes.
The AutoMatch Time also determines the rate at
which delta values written with the Trim will re-
turn to 0 dB (delta value of zero).
The AutoMatch feature works with continuous
controls (such as Volume or Pan) by ramping
their values back to previously automated levels.
There are some stepped controls (for example,
the EQ type in the 1-band EQ plug-in) that pro-
vide more than two discrete steps over their op-
erational range. AutoMatch has no effect on
these controls.
Automation Follows Edit Option
When disabled, automation events are not af-
fected by edits to audio or MIDI notes. When en-
abled, automation events are affected by edits to
audio or MIDI notes.
To disable Automation Follows Edit:
„ Choose Options > Automation Follows Edit.
Any uncoalesced automation on a Send will
still coalesce when the other automation on
its track is coalesced, even if “Include Sends
in Trim Mode” is deselected.
