Use the Sampler Zone pane Edit menu
In Logic Pro, you can use the Zone pane Edit menu to choose a number of sample-handling
commands. Choose any of the following:
Auto-Loop: Analyzes the audio content and automatically sets a loop. You can use the
command multiple times to try different automatic loops.
Auto-Loop within loop area: Analyzes the audio content and automatically sets a loop
within the area defined by the loop start and end markers. You can use the command
multiple times to try shorter automatic loops.
Crop Loop: Crops (cuts) the portion(s) of the sample outside the loop start and end
markers.
Crop Sample: Crops (cuts) the portion(s) of the sample outside the start and end
markers.
Derive Tempo from Loop Length: Calculates a tempo for the audio file based on the
Loop Length. If using the Follow Tempo button does not yield the desired results, you
can choose this option to calculate a revised tempo at which the loop is aligned to the
beat.
Linear or Equal Power Crossfade: Sets the crossfade gain value behavior.
New: Create a new, empty zone. You can add audio to this zone from the File menu or a
drag and drop operation.
Open in Audio File Editor: Opens the selected zone in the Logic Pro Audio File Editor.
Optimize Loop Start: Use to automatically adjust the loop start point to create a smooth
loop cycle.
Optimize Loop Crossfade/End: Use to automatically set crossfade values at the point in
the loop cycle where the loop end and loop start markers cross over. Loop length is not
affected.
Optimize Sample Gain: Analyzes the audio content and sets automatic gain values.
Re-Analyze Transients and Tempo: Re-analyzes the current audio for transient and
tempo changes, following edits you have made.
Retune: Analyzes the audio content and sets the root key and tuning value
automatically.
Write Sample Loop to Audio File: Saves the loop data to the file header of the audio file.
To save the new audio file with a different name, click the Name field and choose the
Rename Current Audio command.

waveform display.
Display Stereo Channels/Mono Sum: Shows a stereo or summed mono waveform view in
the waveform display.
Show Anchor: Displays the absolute start point of the audio file in the waveform display.
