The drop location changes the import behavior:
When you drop an audio file onto the keyboard, it is mapped to that key.
When you drop an audio file onto the Key Mapping Editor above the keyboard, it is mapped to a range of keys. As you drag toward the top of the Key Mapping Editor, the key range expands.
The root key is shown in gold, and the key range (containing the start key and end key) is shown across the keyboard.
In Logic Pro Sampler, drag one or more audio files, regions, or Apple Loops to a software instrument track header with a Sampler instance inserted. Shift-click or Command-click to select multiple files.
When the “Add new zones” dialog appears, drag the items to one of the following:
Sampler (Chromatic Map) maps samples to successive chromatic notes.
Sampler (Optimized Map) maps samples according to analysis of the material.
In Logic Pro, insert Sampler into an instrument channel.
Click the Mapping or Zone buttons (or both) in the Navigation bar to turn on these panes, if they are not shown.
Do one of the following:
In the Zone pane, drag an audio file into the waveform display area.
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 of Zone view.
