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.
• Start-click (Windows) or Control-click
(Mac) the Play button in the Transport win-
dow.
• Press Control+Shift+L (Windows) or Com-
mand+Shift+L (Mac).
• 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.
