In the Group Settings window, select the Editing (Selection) checkbox, followed by the
Phase-Locked Audio checkbox.
The group is now enabled for phase-locked editing.
4
Close the Group Settings window.
When you enable a group of audio tracks for phase-locked editing, a Q button appears
in the track header of each track in the group. This button serves the same purpose as
the Q-Reference checkbox in the Inspector’s Track Parameter box. By turning on a Q
button, all regions on that track contribute their transients as reference points during the
quantization process. By turning off a Q button, you exclude all regions on that track from
contributing their transients as reference points during the quantization process.
To quantize a group of phase-locked audio tracks
1
Display Flex view in the Arrange area by doing one of the following:
• Choose View > Flex View in the Arrange area’s local View menu (or use the Hide/Show
Flex View key command).
• Click the Flex View button in the Arrange toolbar (if visible).
This displays the Flex Mode button in the track header of each audio track in the Arrange
area.
2
Set a flex mode for the grouped tracks by doing one of the following:
• Click the Flex Mode pop-up menu in the arrange track list, then choose the relevant
mode.
• Open the Flex Mode pop-up menu in the Track Parameter box, then choose the relevant
mode.
Your chosen flex mode is assigned to each of the grouped tracks. All audio files on these
tracks are analyzed for transients, adding a transient marker for each detected transient.
Tip: For the best results during the following steps, zoom in on the relevant regions.
3
Open one of the tracks you want to use as Q-reference in the Sample Editor, then check
the transients to make sure they are positioned correctly. You can add or remove transients,
or move incorrectly placed transients, in the Sample Editor. For details, see
Markers to Edit in the Sample Editor
4
Repeat step 3 for any other tracks you want to use as Q-reference.
Note: It’s not necessary to adjust the transients for tracks that are not used as Q-reference.
The timing of these tracks will be adjusted with sample accuracy based on the transients
in the Q-referenced tracks.
5
In the track header of the Arrange area, click the Q button for the tracks to be used as
Q-reference.
