Load and save patterns in Step Sequencer in Logic Pro — Apple Support

Step Sequencer includes a Pattern Browser where you can choose and save patterns and templates. The Pattern Browser contains a variety of premade patterns for drums, bass, keys, and other instrument categories that you can use in your projects. The Pattern Browser also features templates, which include pattern, row, and step settings but with an empty step grid, that you can use as as a starting point for creating patterns.

  Select Next Pattern Page    ⌥`

Moves the next pattern page into the editing window. If a pattern has multiple pages the “next pattern” will cycle.

Sequencers are wonderful experimental playgrounds. I can get lost in them for hours on end.

Pattern creation examples — Apple Support

Edit modes such as Velocity, Note, Octave, and Tie can be useful for creating interesting instrument and melodic patterns.

  Save Pattern    ⇧⌘P

Save the pattern. The command is located in the tool (gear) menu in the Step Sequence. A whole new (old) place to explore.

My first MIDI software (after my CZ Editor) was Opcode Vision — a MIDI sequencer. This modern take on the step sequencer (every pattern is a step sequencer? recursion is us)

Logic Pro Step Sequencer overview — Apple Support

Step Sequencer patterns are contained in pattern regions (in the Tracks area) and pattern cells (in the Live Loops grid). Pattern regions and cells are used primarily on MIDI-based (software instrument, external instrument, and Drummer) tracks. Pattern regions (but not pattern cells) can also be used on audio tracks to automate effect and channel strip parameters. A project can contain any number of pattern regions or cells.

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.
