The resolution for the Scrubber is dependent on
the zoom factor for the scrubbed track.
To scrub multiple audio tracks, do one of the
following:
„ With the Scrubber selected, drag between two
adjacent tracks.
– or –
„
Scrub within a selection that contains multi-
ple tracks.
When scrubbing multiple tracks, only the first
two tracks are heard.
Scrub/Shuttle Mode
When scrubbing normally, you can scrub at nor-
mal playback speeds or slower. Scrub/Shuttle
mode, however, lets you scrub at several times
normal speed, which is helpful in playing
through large ranges and locating material.
To scrub in Shuttle mode (at several times normal
speed):
1 Select the Scrubber tool.
2 While pressing Alt (Windows) or Option
(Mac), drag within the track—left for reverse,
right for forward. The Fast Forward and Rewind
buttons in the Transport window engage.
The distance and speed dragged determine the
speed for the scrubbed audio.
Shuttle Lock Mode
Shuttle Lock mode lets you use the numeric key-
pad to shuttle up to two tracks forward or back-
wards at specific speeds: 5 is normal speed, num-
bers from 6 up to 9 provide increasingly faster
fast-forward speeds, and numbers from 4 down
to 1 provide progressively faster rewind speeds
(4 is the slowest rewind Shuttle Lock speed, 1 is
the fastest). If multiple tracks are selected, only
the first two tracks are shuttled.
To play one or two tracks with the shuttle lock:
1 With Pro Tools HD, make sure the Operation
preference for Numeric Keypad mode is not set
to Shuttle (see “Operation Preferences” on
page 83).
2 With the Selector tool, click in the track where
you want playback to begin. To shuttle on two
tracks, Shift-click in a second track.
3 Press the Start key (Windows) or Control
(Mac) and a number on the numeric keypad:
0–9 (9 is fastest, 5 is normal speed, and 0 stops
shuttling).
Once Shuttle Lock mode is initiated, Fast For-
ward and Rewind become highlighted in the
Transport window.
You can temporarily switch the Selector tool
to the Scrubber tool by Start-clicking (Win-
dows) or Control-clicking (Mac). For finer
resolution, Control-Start-click (Windows)
or Command-Control-click (Mac).
Scrubbing between two audio tracks
The maximum number of channels
scrubbed in Pro Tools is eight, which lets
you scrub a 7.1 track, two stereo tracks
(four channels), but not two 5.1 surround
tracks (12 channels).
