Quickly zoom a portion of the waveform display
The zoom buttons and pinch gestures can be used to zoom the waveform display, but you
can also do the following to quickly zoom a portion of the waveform:
Hold Control and Option, then drag in the waveform display.
The selected area is zoomed to fill the entire waveform display.
Use the Quick Sampler Action or shortcut menu
In Logic Pro, you can use the Action or shortcut menu to choose a number of sample-
handling commands that differ in Classic, One Shot, and Slice modes. Control-click in the
waveform display to access available options from the shortcut menu.
Note: Not all listed commands are available in the shortcut menu. Some commands are
available only in certain modes.
Add Slice Marker: Creates a new slice marker at the current playhead position in the
waveform display.
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.
Copy MIDI Pattern: Analyzes and copies slice markers to the Clipboard. You can paste
the Clipboard contents to a MIDI or instrument track as a new MIDI region. This feature
is ideal for creating perfectly synchronized instrument parts and for drum replacement,
Foley, and other uses.
Create Drum Machine Designer Track: Creates a new Drum Machine Designer track that
contains the current Quick Sampler content.
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.
Delete Slice Marker: Deletes the highlighted slice marker. Move the pointer over a slice
marker to highlight it. You can also double-click a slice marker to remove it.
Derive Tempo from Loop Length: Calculates a tempo for the audio file based on the loop
length. If the Follow Tempo button doesn’t yield the desired results, use this option to
recalculate a loop tempo aligned to the beat.
Display Seconds/Sample/Beats Units: Shows time, sample, or bar/beat values in the
waveform display.
Display Stereo Channels/Mono Sum: Shows a stereo or summed mono waveform view in
the waveform display.
Equal Power Crossfade: Sets the crossfade gain value behavior.
Initialize Synth Parameters: Recalls a neutral setting for all parameters in the Pitch,
Filter, Amp, Mod Matrix, and LFO panes. This provides a “clean slate” when you are
adjusting the parameters of your instrument.
