Split chords in the Piano Roll Editor in Logic Pro — Apple Support

These commands can be used with regions containing chords to separate the top note of each chord (often the melody), or to separate the bottom note of each chord for a bass line. Once selected, the notes can be cut or copied, and pasted into a region on a different track.

Customize the Step Sequencer interface in Logic Pro — Apple Support

You can customize several aspects of Step Sequencer to suit the pattern you are working on and the task you want to accomplish. You can zoom in and out to work in greater detail or view a larger part of the step grid, show or hide step values, color rows and steps, and reorder rows and subrows. You can also save the current pattern configuration as the default template for the channel strip, and revert to the original default template for the channel strip.

Logic Pro Step Sequencer overview — Apple Support

Step Sequencer is inspired by classic hardware step sequencers that have rows of configurable switches or knobs used to generate repeating musical patterns. In Step Sequencer, you 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 (letting you create automation changes over time in the pattern). Each step represents a definable length of musical time–by default, steps are of equal length, but you can change the length for individual rows or steps. You can adjust a wide range of parameters for individual steps, including velocity, pitch, gate time, and more; and edit pattern and row settings including pattern length, row loop start and end points, playback position, and rotation.
