Link mode Link mode is activated by clicking the Link button. It determines the
relationships between windows. An editing window in Link mode shows the same
contents as the top window.
Link button Button featuring the chain link icon in the top left corner of most Logic
windows. It controls the linking between different windows.
local menu Menu in a window that only contains functions that are relevant to that
particular window.
Local Off mode Operating mode on a MIDI keyboard where the keyboard does not
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

loop An audio clip that contains recurring rhythmic musical elements or elements
suitable for repetition. Logic also supports Apple Loops.
Loop function Loop is a Region parameter in Logic that creates “loop repetitions” for
an Audio or MIDI Region. These repetitions will repeat until the song end point, or until
another Region or folder (whichever comes first) is encountered on the same track in
the Arrange window.
LFO Abbreviation for Low Frequency Oscillator. An oscillator that delivers modulation
signals below the audio frequency range—in the bandwidth that falls between 0.1 and
20 Hz, and sometimes as high as 50 Hz or 400 Hz.
lowcut filter A low cut filter is essentially a highpass filter that offers no slope or
resonance controls.
lowpass filter The lowpass filter defines the maximum frequency that can pass
through without being affected, thus controlling the brightness of the sound. Every
signal above this frequency will be cut. The higher the cutoff frequency, the higher the
frequencies that can pass through. A lowpass filter that offers no slope or resonance
controls is a high cut filter.
