This Logic Pro walkthrough from Mastering.com shows how to expand a step-sequenced drum pattern for more variation. Doubling the steps to 32, then 64, gives room to add ghost notes, drop hits like a crash, and drag velocity changes across subdivisions.
Once the pattern feels right, convert it to a MIDI region. This captures every subdivision and velocity tweak from the sequencer into an editable piano roll for deeper editing.
Mixing happens right in the mixer window, where each drum voice sits on its own track with pre-assigned sends and effects. You can pan, EQ, saturate, filter, or limit individual elements or shape the whole drum bus together.
One practical detail: previewing with the dedicated preview button isolates just the sequencer, while spacebar plays the full project with loops and other instruments layered in. Useful to know when you're editing a pattern in context versus checking it on its own.
