Add audio to Quick Sampler in Logic Pro for iPad
Quick Sampler provides two direct methods to add an audio file, Apple Loop, or region. Once you’ve added the file, you can choose different modes to change playback behavior, you can directly edit waveform markers, and you can alter the tonal color and performance characteristics with the synthesis and modulation parameters.
You can also import audio from other locations on your iPad or record audio directly into Quick Sampler. See Import media.
You can quickly replace the sound for Quick Sampler on a software instrument track by dragging an audio file or Apple Loop from the Browser to the track header. When you drag audio material directly into the Quick Sampler waveform display, you can choose whether Quick Sampler uses the original tuning, loudness, looping, and length of the material, or analyzes the material and optimizes its tuning, searches for loop points, and crops silence.
Add an audio file with the Sample name field
In Logic Pro, tap the “Sample name” field at the top center, and choose Browse Samples to open the Browser.
In the Browser, browse to the file you want to import, then drag it into Quick Sampler where two boxes appear.
Original: Adds the audio file to the waveform display, which uses the tuning, loudness, looping, and length characteristics of the source file.
Optimized: Analyzes the source file, optimizing its tuning, loudness, and length, then adds the audio file. If the audio is rhythmic and/or cyclical (looped), Quick Sampler automatically adds loop and crossfade markers to the waveform display. Silence at the beginning or end of the source audio is cropped (cut), shortening the imported audio.
Drag and drop content into Quick Sampler
This task outlines use of content in the Browser. You can also import audio from other locations on your iPad. See Import media.
In Logic Pro, drag an audio file or Apple Loop from the Browser into the Quick Sampler waveform display.
Drop the file into either the Original or the Optimized portion of the display.
Original: Adds the audio file to the waveform display, which uses the tuning, loudness, looping, and length characteristics of the source file.
Optimized: Analyzes the source file, optimizing its tuning, loudness, and length, then adds the audio file. If the contents are rhythmic and/or cyclical (looped), Quick Sampler automatically adds loop and crossfade markers to the waveform display. Silence at the beginning or end of the source audio is cropped (cut), shortening the imported content.
Note: A resampling process is triggered when you drop a region into Quick Sampler. The region is bounced offline and added to the waveform display.
Drag and drop an audio file using Slide Over
You can add files on your iPad to Quick Sampler using Slide Over. See Intro to importing media.
Replace the sound for Quick Sampler on a software instrument track using drag and drop
In Logic Pro, drag an audio file or Apple Loop from the Browser to a software instrument track header with a Quick Sampler instrument inserted.
Save a Quick Sampler setting
In Logic Pro, tap the plug-in menu bar More button 
to access Quick Sampler file commands.
Save: Saves the current instrument state. When you create a new instrument and save it for the first time, you are asked to provide a name. If you have edited an existing instrument and use this command, the existing filename is used and the original instrument is overwritten.
Save As: Saves the current instrument state, but you’re prompted to provide a different filename. Use this command when you want to save a copy or multiple versions of an edited Quick Sampler instrument, rather than overwriting the original version. This command may be useful when you want to save a Quick Sampler setting that is unique to a specific project. Storing this in a location outside of user folders may also be practical for sharing a copy of your Quick Sampler setting with a colleague or friend.
