Use Quick Sampler start, end, loop, fade, crossfade, and
slice markers
In Logic Pro, you can use markers to alter audio playback. You can define the possible
positions for markers using the Snap menu.
Note: Different marker types are shown in each mode.
• Start and end markers: Drag the blue start or end marker to set the sample start and
end point. Playback occurs between these markers. Hold Option, then drag either the
start or end marker to move the entire audio section between these markers.
Note: The Option drag feature works only when the start and end markers are not set to
encompass the entire audio file.
• Loop start and end markers: Drag the yellow loop start or end marker to set loop
boundaries. Playback cycles between these markers when you hold a note. Drag the
yellow shaded area between the loop start and end markers to move the entire loop.
Alternatively, hold Option, then drag either the loop start or end marker to move the
entire loop.
• Crossfade marker: Drag the gray crossfade marker to set the length of the crossfade at
the beginning and end of loop boundaries, smoothing out audible glitches as the loop
cycles across the loop end and start points.
• Fade in/fade out markers: Drag the gray fade in or fade out marker to adjust the length
of the fade at the beginning and end of the audio file segment between the start and
end markers. Hold Option, then drag either fade marker to move both fade markers.
• Slice marker: Shown in Slice mode. Drag any yellow slice marker to set its position. Click
between slice markers to create a new slice marker.
