Continuous Scroll During Playback
(TDM Systems Only)
This scrolling option causes the Edit win-
dow’s contents to scroll continuously past
the playback cursor, which remains in the
center of the window. With this option,
playback is always based on the Timeline
selection (unlike Continuous Scroll With
Playhead).
Continuous Scroll With Playhead
(TDM Systems Only)
This scrolling option causes the Edit win-
dow’s contents to scroll continuously past
the Playhead, which is a blue line in the
center of the window (red when record-
ing).
The Playhead always indicates where play-
back begins when clicking Play in the
Transport window. The Playhead is com-
pletely independent of the Timeline selec-
tion; if the Timeline selection changes, the
Playhead will not update its location when
playback is initiated from the Transport.
When recording, however, the Playhead al-
ways jumps to the Timeline selection.
To move the Playhead to a particular loca-
tion for playback, scroll there in the Ruler
(see “Scrolling in the Ruler” on page 157),
use the Edit window’s horizontal scroll bar,
or type the location into one of the Loca-
tion Indicators or one of the Counters.
With the Playhead enabled, you can still
jump to and play an Edit or Timeline selec-
tion. For details, see “Playing Edit and
Timeline Selections with the Playhead” on
page 173.
Half-Screen Edit Window
When either Continuous Scroll During
Playback or Continuous Scroll with Play-
head is enabled, a half-screen appears at
the far left of the Edit window (before the
beginning of the session).
The Scrubber
The Scrubber allows you to “scrub” up to
two tracks of audio in the Edit Window.
Scrubbing is a technique that originated in
tape editing, where the tape was rocked
back and forth past the playhead at slower
than normal speeds to find a particular lo-
cation (usually for the sake of performing
splices).
While viewing an audio waveform in
Pro Tools can be helpful in visually finding
an edit point, sometimes a waveform (be-
cause of its sonic characteristics) may not
reveal the desired spot in the audio mate-
rial. By scrubbing back and forth over an
edit point in Pro Tools, you can zero in on
the exact edit point you're looking for.
