In Logic Pro Sampler, do one of the following:
In Zone view, choose Zone > New to create a new, empty zone.
In the Key Mapping Editor, press and hold Command-Shift, then drag the pointer to create a new, empty zone.
A new group is shown in the Mapping pane and a zone is automatically added to the group.
Click the Options button at the lower left of the File Selector window to show or hide the checkboxes and Play button.
Select “Hide used audio files” to dim the names of files used in the currently loaded sampler instrument.
Select “Preview audio file in Sampler Instrument” to temporarily replace the sample files in the currently selected zone. The zone is not directly triggered by selecting this option, but it can be triggered by playing MIDI notes while the File Selector window is open—and different files are chosen. The selected sample can be heard as part of the zone, inclusive of all synthesizer processing (filters, modulation, and so on).
To preview looped playback of the currently selected audio file, click the Play button at the lower right of the File Selector window. The Play button label changes to Stop during playback.
You can step through files by using the Down Arrow key, or by clicking them, to audition each file in turn.
Click the Stop button to stop playback.
When you find an audio file you want to use, click the Open button to add it to the zone.
When the audio file is loaded, the sample name is displayed in the Name field for the zone in the Audio File column in Zone view.
