You can create and edit automation data directly in the Piano Roll Editor. For detailed information about using automation, see Automation overview.
When track-based automation is displayed in the Automation/MIDI area, the displayed automation curve is identical to the automation curve displayed in the automation lane in the Tracks area. Any adjustments to the automation curve made in either location is reflected immediately in the other. However, with region-based automation, you can choose to display either the automation curve associated with the region in the Tracks area automation lane or the MIDI data associated with individual notes. Therefore, with region-based automation it is possible to have the automation lane in the Tracks area showing the automation curve associated with the region and the Automation/MIDI area displaying MIDI data associated with each note (or vice versa).
Note: Region-based automation is effectively the same as MIDI Draw in previous versions of Logic Pro. If you had MIDI Draw data in a project created in a previous version of Logic Pro, it appears as region-based automation data.
