Use Flex Time and Pitch in the Logic Pro for Mac Audio Track Editor
You can adjust the timing and pitch of audio regions in the Audio Track Editor using Flex Time and Pitch. Using the Audio Track Editor for editing the timing and pitch of audio allows you to keep Flex mode off in the Tracks area, which is useful when you want the Tracks area to show automation, for example. In addition, the Audio Track Editor offers two tools for Flex Pitch, the Volume tool and Vibrato tool, that aren’t available in the Tracks area. These tools are described in Edit the pitch of audio in the Audio Track Editor.
