The Smart Tool with Stereo and
Multichannel Tracks
When using the Smart Tool on stereo and mul-
tichannel tracks, individual channels cannot be
independently edited. All edits affect all chan-
nels as a whole.
Tool switching for the Smart Tool in stereo and
multichannel tracks is determined by the posi-
tion within the entire track, and not within in-
dividual channels.
Using the Scrubber Tool
The Scrubber tool lets you “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 location (usually for cutting
and splicing).
While viewing an audio waveform in Pro Tools
can be helpful in visually finding an edit point,
sometimes a waveform display (because of its
sonic characteristics) may not reveal the desired
spot in the audio material. By scrubbing back
and forth in Pro Tools, you can listen and locate
an exact edit point.
When the Edit Insertion Follows Scrub/Shuttle
option is enabled in the Operation Preferences
page, the edit cursor automatically locates to the
point where scrubbing stops.
When the Scrolling option is set to Continuous
(Pro Tools HD and LE with DV Toolkit 2 only) or
Center Playhead (Pro Tools HD only), clicking
with the Scrubber in a track’s playlist centers the
Edit window around that point, and moves the
Playhead there. With these Scrolling Options,
scrubbed material moves past the Playhead,
which remains stationary and centered.
To scrub a single audio track:
1 Select the Scrubber tool.
2 Drag within the track: left for reverse or right
for forward.
The distance and speed with which you drag
(with either the mouse, or the scrub wheel on a
control surface) determine the length and speed
of the scrubbed audio. Audio from the scrubbed
track is routed to its output, along with any ef-
fects assigned to the track.
Scrubbing is only supported for audio
tracks. MIDI and Instrument tracks cannot
be scrubbed.
