You can fade in the beginning of audio regions, and fade out the end of audio regions (including audio Apple Loops) using either the Fade tool or the Fade In and Fade Out parameters in the Region inspector.
Fades are visible only when you have zoomed in enough to see the waveform in the audio region.
In Logic Pro, select the Fade tool from the Tool menu in the menu bar for the Tracks area.
In the Tracks area, do one of the following:
Drag over the start or end point of an audio region.
A fade-in or fade-out is created. The length of the fade drag area determines the length of the fade, so a longer drag area results in a longer fade time, and a shorter drag area, a quick fade.
Drag over the end point of one audio region and the start point of the region that follows.
This technique works even if the two sections don’t directly adjoin each other.
With the Fade tool selected, you can edit fades on regions after you make them.
In Logic Pro, select one or more regions.
Set the value for the Fade In or Fade Out setting in the Region inspector by dragging the pointer vertically, or double-clicking and entering a value.
Fades created using the Fade tool and the Region inspector are interactive. After you create a fade using the Fade tool, for example, you can adjust the fade using the Region inspector Fade In or Fade Out parameters.
In Logic Pro, select one or more regions.
Use the “Apply Last Fade or Fade Marquee Selection” key command.
The “Apply Last Fade or Fade Marquee Selection” command applies the following region parameters to the selected regions:
Fade In/Speed Up–Time
Fade In/Speed Up–Curve
Fade Out/Slow Down–Type
Fade Out/Slow Down–Time
Fade Out/Slow Down–Curve
Changing the Fade Out/Slow Down–Type from “Out” to “EqP Crossfade” (Equal Power Crossfade) depends on whether the selected region is followed by an adjacent region (which requires EqP Crossfade) or a gap (which requires Out). For similar reasons, changing from any “Crossfade” type to “Out” depends on whether the selected region is followed by an adjacent region or a gap.
In Logic Pro, make a marquee selection to part of one or more regions.
Use the “Apply Last Fade or Fade Marquee Selection” key command.
Logic Pro analyzes each marquee selection, and applies one of the following fade types for every affected track:
If the marquee selection encloses one region end which is followed by a gap, a Fade Out is applied from the marquee selection start to the region end.
If the marquee selection starts later than the region start and ends exactly on the region end (within the same pixel, or so), a Fade Out is applied from the marquee selection start to the region end.
If the marquee selection encloses exactly one junction between two adjacent regions (starts later than the first region start, ends earlier than the second region end), an Equal Power Crossfade is applied from the marquee selection start to the marquee selection end, with the crossfade pivot on the region junction.
If the marquee selection encloses a region start, which follows a gap, or if the marquee selection starts on the region start and the marquee selection ends before the region end, a Fade In is applied from the region start to the marquee selection end.
