To set the QuickPunch Crossfade Length:
1 Choose Setups > Preferences, and select 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 Done.
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 later be edited in the
same manner as standard crossfades. For details,
see “Using Crossfades” on page 295.
QuickPunch Guidelines for
TDM Systems
When using QuickPunch on TDM systems, 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 sys-
tem configured for 128 voices can simulta-
neously record on up to 64 mono tracks with
QuickPunch (or 32 stereo tracks).
If the required number of voices for the record-
enabled tracks is not available when switching
to QuickPunch mode, you will be 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:
■ Set voice assignments for tracks to Off.
– or –
■ Make tracks inactive.
As necessary, voices in use by other tracks,
which are not record-enabled, may be “stolen”
while recording with QuickPunch. 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-en-
abled
• Auto-voiced tracks that are not record-en-
abled
• Auto-voiced tracks that are record-enabled
If the session has plenty of available voices, you
may have no trouble using QuickPunch with
auto-voiced tracks. However, if you are running
out of voices, and want to ensure that a track
will be heard when recording with QuickPunch,
assign it a voice.
QuickPunch and Auto Voice
(TDM Systems Only)
When using QuickPunch with a Pro Tools TDM
system configured for the maximum 128- or 64-
voices, make sure to set the voice assignment for
each audio track to Auto. This ensures that
Pro Tools will automatically handle the distri-
bution of voices between each set of voices. For
