Regions
Regions are the building blocks of a project. Each time you make a recording, drag an
Apple Loop to the Tracks area, or add a media file to your project, a region representing
the recording or file appears in the Tracks area. Different types of regions correspond to
different track types and types of material.
Audio regions refer to (point to) an underlying audio file (a recording made in Logic
Pro, an audio Apple Loop, or an imported audio file). An audio region can represent the
entire audio file or only a portion of one. When you edit the region in the Tracks area or
the Audio Track Editor, the original audio file is not changed.
MIDI regions contain MIDI data for notes and other MIDI events, such as controller and
program change information. They are stored as part of the project, but can also be
saved as individual files.
In the Tracks area, you can move, copy, and work with both audio and MIDI regions in a
variety of ways to build your arrangement. You can also edit audio regions in the Audio
Track Editor, and edit MIDI regions in the Piano Roll Editor (and the Score Editor).
When
Show Advanced Tools is selected in the Advanced preferences pane, you can edit the
source audio files for audio regions in the Audio File Editor.
For more information about arranging regions in the Tracks area, see Logic Pro Arranging
overview. For information about editing audio regions in the Audio Track Editor, see The
Audio Track Editor in Logic Pro. For information about editing MIDI regions in the Piano Roll
Editor, see Overview of the Piano Roll Editor in Logic Pro.
For more information about working with regions, see Logic Pro regions overview.
Patches
You can control the sound of the tracks in your project using patches. A patch can contain
one or more channel strips, each with its own settings and plug-ins, as well as a set of
Smart Controls. Patches can also contain auxiliary channel strips for more complex routing.
You can choose a patch for a track in the Library when you create the track, and choose a
different patch later while you’re working. Custom patches can be saved in the Library.
For more information about working with patches, see Logic Pro patches overview.
