Center Playhead Scrolling
(Pro Tools HD Only)
When this scrolling option is selected, the Edit
window’s contents scroll continuously past the
Playhead, which is a blue line in the center of the
window (or a red line when recording).
The Playhead indicates where playback begins
when clicking Play in the Transport window.
To move the Playhead to a particular location
for playback, you can scroll there in a ruler (see
“Scrolling in a Timebase Ruler” on page 573),
use the Edit window’s horizontal scroll bar, or
type the location into one of the Edit Selection
indicators or one of the Counters.
Moving the Playhead with these methods does
not update the Timeline selection. However, up-
dating the Timeline selection automatically
moves the Playhead to the Timeline insertion
point.

Playing Timeline and Edit
Selections with the Playhead
(Pro Tools HD Only)
When the Scrolling option is set to Center Play-
head, selections in the Timeline do not deter-
mine when playback begins. The Playhead itself
denotes where playback begins when clicking
Play in the Transport.
Timeline and Edit selections, however, can still
be played when the Playhead is enabled.
To play an Edit selection with the Playhead
enabled:
1
Deselect Options > Link Timeline and Edit Selec-
tions.
2
Select Options > Scrolling > Center Playhead.
3
With the Selector or Time Grabber tool, make
a track selection.

enabled:

Deselect Options > Link Timeline and Edit Selec-
tions.
2
Select Options > Scrolling > Center Playhead.
3
Drag with the Selector tool in any Timebase
ruler to set the play range.
4
Choose Edit > Selection > Play Timeline.
The Playhead jumps to the Timeline selection
and plays it from beginning to end, and then
stops.
Moving the Playhead
When the Scrolling option is set to Center Play-
head, the Playhead can be moved forward or
back to the next region boundary in the selected
track.
To move the Playhead through a track’s region
boundaries:
1
Make sure the Tab to Transients button is not
enabled (see “Tabbing to Transients” on
page 570).
2
Click in the track with the Selector tool.
3
Do one of the following:
• Press Tab to move the Playhead forward to
the next region boundary.

• Loop Playback mode
• Dynamic Transport mode
Normal Playback Mode
Normal Playback mode is simply when none of
the other Playback modes are selected. In Nor-
mal Playback mode, Pro Tools plays back at the
session sample rate.

Half-Speed Playback Mode
Use Half-Speed Playback mode to learn or tran-
scribe difficult passages in recorded tracks.
To play at half-speed:
1
Do one of the following:
• Shift-click the Play button in the Transport.
– or –
• Right-click the Play button in the Transport
and select Half-Speed. Then click Play to
start Half-Speed Playback.
2
Click Stop in the Transport to stop playback.
Prime for Playback Mode
When playing back a large number of tracks,
Pro Tools may take a little longer to actually
start playback. To avoid this delay, put Pro Tools
in Prime for Playback mode before starting play-
back.
To enable Prime for Playback mode and start
playback:
1
Do one of the following:
• Option-click (Mac) or Alt-click (Windows)
Play in the Transport to put Pro Tools in
Prime for Playback mode.
– or –
• Right-click the Play button and select Prime
for Playback.
The Stop button lights and the Play button
flashes.
2
To begin playback instantaneously, click Play.
3
Click Stop to stop playback.
Loop Playback Mode
When Loop Playback mode is enabled, the se-
lected track range repeats on playback. If there is
no selection, playback occurs normally from the
current Cursor location.
Looping playback is a useful way to check the
rhythmic continuity of a selection when work-
ing with musical material. If you’re working
with one-bar selections, you can loop playback
to see if the material loops cleanly. If it seems to
skip, you should then adjust the length of the
selection until it works “musically” within the
context of the playlist and the other tracks.
To loop playback of a selection:
1
Select Options > Link Timeline and Edit Selection.
2
With the Selector tool, select the track range
you want to loop.
3
Enable Loop Playback by doing one of the fol-
lowing:
• Select Options > Loop Playback.
• Right-click the Play button in the Transport
window and select Loop from the pop-up
menu.
• Control-click (Mac) or Start-click (Win-
dows) the Play button in the Transport
window.
• Press Command+Shift+L (Mac) or Con-
trol+Shift+L (Windows).
• With the Numeric Keypad mode set to
Transport, press 4 on the numeric keypad.
You can also play at half-speed by pressing
Shift+Spacebar.
When synchronizing to time code, use
Prime for Playback mode to play back large
numbers of tracks. This decreases the time it
takes to lock to time code.
A selection must be at least 500 ms in
length for it to loop on playback.

Chapter 20: Playing Back Track Material 417
When enabled, a loop symbol appears in the
Play button in the Transport window.
4
Click Play in the Transport window.
Playback begins from the pre-roll point (if en-
abled) and continues to the selection’s end
point, where it loops back to the selection’s start
point.
5
Click Stop in the Transport window to stop
playback.
Loop Playback and Audio Recording
Looping playback does not enable loop record-
ing. Use Loop Record mode to loop during re-
cording (see “Loop Recording Audio” on
page 461).
Dynamic Transport Mode
Dynamic Transport mode lets you decouple the
playback location from the Timeline selection.
This means that you can start playback from
anywhere on the Timeline without losing your
Timeline or Edit selections. For example, you
can use Dynamic Transport mode in conjunc-
tion with Loop Playback mode to quickly audi-
tion loop transitions.
When Dynamic Transport mode is enabled, the
Main Timebase ruler expands to double-height
and reveals the new Play Start Marker. The Play
Start Marker determines where playback starts
when the Transport is engaged. You can posi-
tion the Play Start Marker independently of the
Timeline Selection. The Play Start Marker can be
repositioned during playback and playback con-
tinues from the new location.
To enable or disable Dynamic Transport mode, do
one of the following:
ɸ
Select or deselect Options > Dynamic Transport.
ɸ
Right-click the Play button in the Transport
window and select Dynamic Transport from the
pop-up menu.
ɸ
Press Command+Control+P (Mac) or Con-
trol+Start+P (Windows) to toggle Dynamic
Transport mode on or off.
Loop Playback enabled
Enabling Dynamic Transport mode auto-
matically disables Link Timeline and Edit
Selection, and automatically enables Loop
Playback mode.
Center Playhead Scrolling (Pro Tools HD
only) and Dynamic Transport mode cannot
be used at the same time. Selecting Center
Playhead Scrolling disables Dynamic
Transport mode (if it is enabled). Likewise,
enabling Dynamic Transport mode when
Center Playhead Scrolling is selected auto-
matically changes the Scrolling option to
No Scrolling.
