QuickPunch/TrackPunch Crossfade
Length
Pro Tools can automatically write a crossfade for
each punch point when using QuickPunch. The
length for these crossfades is set with the Quick-
Punch Crossfade/TrackPunch Length option in
the Editing Preferences page.
To set the QuickPunch Crossfade Length:
1
Choose Setup > Preferences and click the
Editing tab.
2
Enter a new value (in msec) for the Quick-
Punch/TrackPunch CrossFade Length.
A good general-purpose crossfade length for
punches is 10 milliseconds. If you set the prefer-
ence to zero, Pro Tools will not create any cross-
fades at the punch-in/out points.
3
Click OK.
If a value other than zero is specified for the
QuickPunch/TrackPunch Crossfade Length,
Pro Tools writes a pre-crossfade at the punch-in
point (which occurs up to but not into the
punched region boundary), and a post-crossfade
at the punch-out point (which occurs after the
punched region).
Even if the QuickPunch/TrackPunch Crossfade
Length is set to zero, Pro Tools always executes a
4 millisecond “monitor only” crossfade (which
is not written to disk) to avoid distracting pops
or clicks that might occur as you enter and exit
record mode.
QuickPunch crossfades can be edited in the
same manner as standard crossfades (see “Using
Fades” on page 465).
QuickPunch Guidelines for
Pro Tools HD
When using QuickPunch with Pro Tools HD,
two voices are required for each record-enabled,
mono track. This means that you can record up
to half the total number of voices available on
your system. For example, a Pro Tools|HD Accel
system configured for 192 voices can simulta-
neously record on up to 96 mono tracks with
QuickPunch (or 48 stereo tracks).
If the required number of voices for the record-
enabled tracks is not available when switching
to QuickPunch mode, you are prompted to free
up the necessary voices.
To free up voices on tracks that are not record-
enabled, and do not need to be heard while
recording, do any of the following:
■
Set voice assignments for tracks to Off.
■
Make tracks inactive.
■
Group all RTAS plug-ins before TDM plug-ins.
Voices that are in use by others track, but not
record-enabled, may be “stolen” while record-
ing with QuickPunch as necessary. Priority for
tracks while recording with QuickPunch are as
follows:
• Tracks with assigned voices that are not
record-enabled.
• Tracks with assigned voices that are record-
enabled.
• Tracks with Dynamically Allocated Voicing
that are not record-enabled.
• Tracks with Dynamically Allocated Voicing
that are record-enabled.
