If the session has plenty of available voices, you
may have no trouble using QuickPunch with
tracks using Dynamically Allocated Voicing.
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 Dynamically Allocated
Voicing
(Pro Tools HD Only)
When using QuickPunch with a Pro Tools|HD
system configured for its maximum number of
voices, make sure to set the voice assignment for
each audio track to Dyn (for Dynamically Allo-
cated Voicing). This ensures that Pro Tools will
automatically handle the distribution of voices
between each set of voices. For example, for a
192-voice configured Pro Tools|HD Accel sys-
tem, Dynamically Allocated Voicing distributes
voices evenly across four sets of voices (1–48,
49–96, 97–144, and 145–192).
If you do not use Dynamically Allocated Voic-
ing, the voices must be evenly distributed be-
tween all DSP engines. For example, to use
QuickPunch on 32 tracks without Dynamically
Allocated Voicing, tracks 1–16 must be assigned
to voices 1–16 and tracks 17–32 must be as-
signed to voices 33–48.
QuickPunch Guidelines for
Pro Tools LE
For Pro Tools LE systems, up to 16 mono, or 8
stereo audio tracks can be simultaneously re-
corded with QuickPunch in addition to the
maximum number of mono tracks supported by
your Pro Tools LE system (see "Pro Tools LE Sys-
tem Capabilities" on page 10).
For Pro Tools LE with DV Toolkit 2 and Pro
Tools LE or M-Powered with Music Production
Toolkit, up to 24 mono or stereo audio tracks
can be simultaneously recorded with Quick-
Punch. On these systems, the combination of
audio tracks and QuickPunch cannot be greater
than 48.
QuickPunch uses CPU processing power,
and may reduce the number of tracks and
plug-ins you can use.
