Logic Pro Step Sequencer overview – Apple Support
Each pattern region or cell functions as an independent step sequencer, with its own configuration and settings. You can copy and move pattern regions like other regions in the Tracks area, while pattern cells can be copied, moved, triggered, and queued like other Live Loops cells. You can modify pattern region and cell parameters in the Region inspector or Cell inspector, respectively.
