Slice and convert Audio Loops to a Sampler track in Logic Pro

Logic Pro Tutorials, 18 October 2011

Learn how to quickly convert your audio loops in the arrange page into a sliced EXS24 sampler track to enable MIDI editing, tempo changes and loop variation in this lesson here at Logic Cafe.

This lesson uses Logic Pro's transient detection engine to quickly create a sampler track with individual hits or samples allocated to MIDI notes which can be played back or sequenced from the EXS24 in the piano roll.

Note: The audio file used in the lesson is Modern Rock Drums 1, taken from the Apple Loops library shipped with Logic Pro 9. This enables you to mimic the session before trying it out on your own audio files if you so wish.

Step 1

In the arrange window, click on the audio object you wish to edit in this session.

Step 2

In the arrange page, click on the Audio tab from the drop down menu and select Convert Regions to New Sampler Track

Step 3

In the resulting dialogue box, click the button labeled Transient Markers to make sure that the file is sliced using Logic Pro's Transient detection engine.

Step 4

Click in the Trigger Note Range drop down menu to select the point at which you would like your samples to begin on the piano roll. In this example note C1 is selected.

Note: C1 is usually the lowest note when dealing with drum samples and often the first pad on hardware drum pad controllers such as the Akai MPD series etc.

Step 5

Click OK.

Step 6

You will now see that Logic Pro has automatically muted the original audio file and created an EXS sampler track underneath on the arrange page. The original file has been copied and split into several smaller audio files, each of which is now allocated to a key. The MIDI file created mirrors the transients detected by Logic Pro and each sample is arranged chromatically (every half step up the keyboard).

You can now edit your original sample as MIDI.
