Start and End Fields
The Transport window can be resized to

pre- and post-roll settings. When setting a
record or play range, it is reflected in these
fields.
You can enter locations in the start and
end fields to set the record or play range.
The Playback Markers in the Ruler are up-
dated accordingly.
To set the record range by entering start/end
times in the Transport window:

Setting Pre/Post-Roll
Pre- and post-roll times appear as flags in
the Ruler. When pre- and post-roll are en-
abled, the flags are green, otherwise they
are gray.
Pre- and post-roll amounts can be entered
in the Transport window, set from a track’s
playlist or Timebase Ruler, or by recalling a
Memory Location.
▲ For TDM systems, recording with pre/post-
roll requires two voices for each record-en-
abled track. In addition, to simultaneously
record on 32 tracks with pre/post-roll on a
Pro Tools 24 MIX system (which allocates
voices to either of two DSP engines, 1–32 and
33–64), the tracks must be evenly distributed
between the two DSPs (for instance, tracks
1–16 assigned to voices 1–16 and tracks
17–32 assigned to voices 33–48).
