QuickPunch/TrackPunch Crossfade Length Spec-
ifies a default length for crossfades created by
QuickPunch or TrackPunch recordings. Cross-
fades occur before the punch in and after the
punch out.
Preserve Fades when Editing This option pre-
serves fade-ins and fade outs, and converts sep-
arated crossfades into corresponding fade-ins
and fade-outs.
Default Fade Settings
Fade In Selects the default envelope shape for
fade-ins.
Crossfade Selects the default envelope shape for
crossfades.
Fade Out Selects the default envelope shape for
fade-outs.
REX/ACID Selects the default envelope shape for
fades and crossfades between regions ("slices")
in imported REX and ACID files.
Automatically Create Fades for Imported REX
and ACID files
When selected, this option automatically ap-
plies fades between regions ("slices") within im-
ported REX and ACID files to minimize clicks or
pops during playback. If there is overlap be-
tween slices, a crossfade is applied. If there is a
gap between slices, a fade out is applied to the
end of the first region. (The fade shapes applied
to REX/ACID files follow the Default Fade Set-
tings for REX/ACID.)
Levels of Undo
This preference sets the maximum number of
actions that can be undone with the multiple
undo feature. Setting this to a lower number can
speed up the performance of slower computers.
Pro Tools supports up to 32 Levels of Undo.

Setup Section
Sends Default to –INF When selected, the initial
fader level of newly-created sends is set to –∞
(no audible signal level). When not selected, the
initial fader level of newly-created sends is set to
0 dB.
Send Pans Default to Follow Main Pan When se-
lected, newly created sends have Follow Main
Pan turned on, so the Send Pan controls follow
the pan controls of the track. When not se-
lected, newly created sends have Follow Main
Pan turned off.
Link Mix and Edit Group Enables When selected,
this option links enabling and disabling of Mix
and Edit Groups. For example, enabling Group
A in the Mix Window automatically enables
Group A in the Edit window.
Use Absolute Pan Linking This option affects be-
havior of grouped pan controls.
• When selected, grouped pan controls do
not maintain relative offsets when any of
the grouped pan controls is adjusted. All
grouped pan controls snap to the absolute
value of the adjusted control.
