Step 1: Create Session Drummer Track(s)

Click the + to add a new track in your Logic project.

Select Session Player - Drummer and click Create.

Select a Drum Kit from the Library on the left. You can also select a Multi-Channel kit from the bottom of the list which creates a track stack of all the individual drum tracks, which you can further refine.

Tweak drumming style, complexity, intensity, and other details to your liking.

Ensure the drum track sounds good in the context of your overall project and is in rhythm.

Proceed to Step 2.
