150 Glossary
interface 1) A hardware component such as a MIDI or audio device that allows Logic
to “interface” (connect) with the outside world. You need an audio or MIDI interface to
get sound/MIDI into and out of your computer. Also see audio interface. 2) A term that
is used to describe Logic’s graphical elements that can be interacted with. An example
would be the Arrange window, where graphical interface elements such as Regions are
interacted with to create an arrangement, within the overall Arrange interface.
key The scale used in a piece of music, centered around a specific pitch. The specified
pitch is called the root of the key.
key command Function which can be executed by pressing a specific key (or key
combination) on your computer keyboard or MIDI controller.
latency You may notice a delay between playing your keyboard and hearing the
sound. This is a form of latency. A variety of factors contribute to latency including
audio interface, audio, and MIDI drivers. One factor under you control, however, is the
I/O buffer size, which is set in the Audio > Audio Hardware & Drivers preferences.
legato Method of musical performance that smoothly connects one note to the next.
level meter A meter that lets you monitor audio output levels from your computer.
You use the level meters in Logic when recording, arranging, and editing audio files.

directly play its own integrated sound generator. This is useful when using it as a
master keyboard in a MIDI setup with Logic.
Locators Lower two sets of numbers, displayed to the right of the Transport buttons in
the Transport window. The number on top is the left Locator; the number on bottom
the right Locator. The Left and Right Locators control the time-range which Logic’s
playback will cycle or skip during playback. The Locators also can be used to define the
editing area for certain functions.
Logic Setup Assistant A utility that guides you through the process of setting up your
Macintosh, audio, and MIDI hardware to work with Logic. The Logic Setup Assistant can
be run at any time by choosing the Preferences > Start Logic Setup Assistant menu
