Summary
You have now been introduced to what the Step Sequencer is and how its Pattern Regions, Rows, and Steps work together. Like all the MIDI editors' local inspectors, the Step Sequencer local inspector is very helpful. You learned how to alter existing patterns or create your own and save them so that they are available to you in any project with the Pattern Browser.
There are three different Row types: Notes, Melodic, and Automation. Pattern Loops are the latest entry into the Loop Browser choices, for drag and drop part creation.
In the next chapter, we will become familiar with Logic Pro's Sampler, formerly the EXS24, Quick Sampler, and Auto Sampler.
