Key Concepts
Project:  A Logic document. It contains all MIDI regions and references to the audio
les to be played back. A project le is saved within a project folder, which can
contain the project’s audio les and other assets (such as video and sample les).
Saving a project with assets simplies archiving and exchanging projects but
increases the project folder’s size.
Audio track:  A lane in the Arrange area that is used for the playback, recording, and
editing of audio regions.
Audio region:  A rectangular object that resides on an audio track. It can be freely
edited, and its boundaries correspond to start and end points within the underlying
audio le it is associated with.
Software instrument track:  A lane in the Arrange area that is used for the playback,
recording, and editing of MIDI regions, which play internal software instruments.
MIDI region:  A rectangular object that resides on a software instrument track. It
contains MIDI events—individual notes or commands—that are generally created
with a MIDI keyboard.
Arrange window:  The primary working window of Logic Pro. It incorporates all
working areas and editors, including the Arrange area.
Arrange area:  The primary working space of Logic Pro. It is used to record, edit, and
arrange the audio and MIDI regions of a project.
Inspector:  Area at the left edge of the Arrange window and editors, containing the
Parameter boxes and channel strips of the selected track.
Toolbar:  Area at the top of the Arrange window where you can access or hide certain
onscreen areas or carry out key functions.
