Replace or double drum sounds in Logic Pro — Apple Support

Using drum replacement, you can replace individual drum sounds on an audio track without re-recording the entire track. To replace or double the drum sounds, you use an audio track that contains a recording of a single drum (or other percussion instrument) to create a software instrument track with matching MIDI trigger notes. The software instrument track plays drum samples using the Sampler instrument.
