Create automatic crossfades
Logic Pro can automatically create crossfades on overlapping audio regions on a track to smoothly segue between adjacent (or overlapping) audio regions.
Turn on automatic crossfades
Choose the X-Fade setting from the Drag pop-up menu in the Tracks area menu bar. (See Control positioning with drag modes.)
You can also create crossfades manually—as well as fade-ins and fade-outs—using the Fade tool, the Fade parameters in the Region inspector, or the shortcut menu of an existing fade area. For information, see Create fades and Edit fades.
You can simultaneously adjust the fade parameters for all selected audio regions.
Note: The Fade parameters are nondestructive, unlike the fade functions available in the Audio File Editor, which change the original audio file.
