Crossfade Preview Pre-Roll This option specifies
the amount of pre-roll to be added when you are
auditioning crossfades in the Fades dialog.
Crossfade Preview Post-Roll This option speci-
fies the amount of post-roll to be added when
you are auditioning crossfades in the Fades dia-

QuickPunch/TrackPunch Crossfade Length Spec-
ifies a default length for crossfades created by
QuickPunch or TrackPunch (Pro Tools HD only)
recordings. Crossfades 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.
Fade Out Selects the default envelope shape for
fade-outs.
Crossfade Selects the default envelope shape for
crossfades.
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.
