Glossary 977
chorus effect Effect achieved by layering two identical sounds with a delay, and
slightly modulating the delay time of one, or both, of the sounds. This makes the audio
signal routed through the effect sound thicker and richer, giving the illusion of multiple
voices.
click Metronome, or metronome sound.
Clipboard The Clipboard is an invisible area of memory, into which you cut or copy
selected data, using the Edit menu. Data stored in the Clipboard can be pasted to
different positions. In Logic Pro, the Clipboard can be used to exchange data within a
single project or between projects.
clipping (in digital recording) Feeding too much signal through a channel strip,
thereby exceeding the limit of what can be accurately reproduced, results in a distorted
sound known as clipping. Logic Pro audio channel strips feature a clip detector, which
indicates signal level peaks above 0 dB.
clock Electrical synchronization impulse, transmitted every 1/96 note. Was used in
older drum machines before the advent of MIDI (MIDI Clock is a modern
implementation of simple clock signals. It runs at 24 ppqn—pulses per quarter note—
or 96 pulses per note).
cloned audio region A cloned audio region is a pointer to the original region.
Whenever you adjust the start or end points of any of these cloned regions, all other
cloned regions will also be adjusted in the same way.
comb filter effect A short delay of feedback that emphasizes specific harmonics in a
signal is generally termed a comb filter. The name is derived from the appearance of a
frequency spectrum graphic, which resembles the teeth of a comb.
compressor An effect that restricts the dynamic range of an audio signal (also see
expander).
comping A process where multiple recording takes are compiled into a single perfect
take (see takes).
Content Link mode The chain link button found at the top left of most Logic Pro
windows features three modes. Content Link mode is useful for situations where
multiple MIDI regions are horizontally aligned along a single track, and you are viewing
the MIDI region contents in the Piano Roll Editor, for example. In this scenario, the
Piano Roll Editor will only show the contents of the selected MIDI region. Should you
wish to view the contents of each MIDI region (selected or not) in the Piano Roll Editor
as the project plays, you will need to activate Content Catch mode.
controller MIDI data type. As examples: sliders, pedals, or standard parameters like
volume and panning. The type of command is encoded in the first data byte, the value
being sent or received is encoded in the second data byte.
