Overview of Step Sequencer in Logic Remote on iPhone
With Step Sequencer in Logic Pro, you can create patterns by editing multifunctional steps in the step grid. Each row controls either a sound (which can be a drum kit piece, a note on an instrument, or a range of notes) or an automation parameter (to create automation changes over time in the pattern). Each step represents a definable length of musical time. You can adjust a wide range of parameters for individual steps, including velocity, pitch, and gate time; and edit pattern and row settings including pattern length and playback position.
Logic Remote lets you create, edit, and play Step Sequencer patterns from your device. The Step Sequencer interface in Logic Remote includes the following:

Step grid: The main working area where you turn steps on and off, and graphically edit step settings using edit modes.
Row headers: Each header contains a row icon, a disclosure arrow to show subrows, Mute and Solo buttons, and row settings.
Edit Mode selector: You can choose the edit mode for the pattern, and quickly switch between Step On/Off and other edit modes. See Use edit modes.
Page overviews: For patterns longer than 16 steps, view and quickly switch to different parts of the pattern.
Pattern Settings button: View and change settings for the entire pattern, including pattern length, step rate, playback mode, and more.
Preview button: Play the pattern.
Pattern regions and pattern cells
In Logic Pro, Step Sequencer patterns are contained in pattern regions (in the Tracks area) and pattern cells (in the Live Loops grid.) 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. Patterns can include both note rows (which generate MIDI note events), and automation rows (which generate stepped automation events for an automatable parameter). Each row can have its own length, step rate, playback mode, start offset, and other settings. Patterns can be from 12 to 64 steps in length, allowing for different time signatures and multiple bar patterns.
Edit modes
You can control different attributes of the note or event triggered by a step using edit modes. Some edit modes apply to only one row type, while others are common to both types. For note rows, you can change the velocity, pitch, gate time, number of note repetitions in a step, and other attributes. For automation rows, you can change the value of the automated parameter. Edit modes common to both row types include skipping and tying steps, changing the loop start and end point, and changing the step rate. For more information, see Use edit modes.

You select the edit mode for all rows in the pattern using the Edit Mode selector. You can also view and edit multiple edit modes per row using subrows. Rows always match the edit mode selected in the Edit Mode selector, but you can choose any unused edit mode for a subrow. You can add and delete subrows as needed.
