channel strip A virtual representation of a channel strip on a mixing console. Each channel
strip contains a number of similar controls, includinga Mute button, Volume fader, Pan/
Balance knob, Input slot, Output slot, Send slots, Effect slots, and Format button. The
channel strips shown in the inspector and in the Mixer are used to process audio or MIDI
information that is routed from tracks.
channel strip setting Refers to the routing of a channel strip, including all inserted
effects or instruments (plus their presets). Logic Pro allows these settings to be saved and
recalled, which simplifies the task of re-creating complex serial effect routings between
channels or projects.
chorus effect An 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 The sound a metronome makes, also sometimes used to indicate the metronome.
clipping In digital recordings, the result of feeding too much signal through a channel
strip, thereby exceeding the limit of what can be accurately reproduced and producing a
distorted sound. Logic Pro audio channel strips feature a clip indicator, which indicates
signal level peaks above 0dB.
clock An electrical synchronization impulse, transmitted every 1/96 note. A clock 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 pulses per quarter note (ppqn), or 96 pulses per note.
cloned audio region A pointer to the original audio region. When you adjust the start or
end point of a cloned region, all other regions cloned from the same original region are
adjusted in the same way.
comb filter effect The general term for a short delay of feedback that emphasizes specific
harmonics in a signal. The name is derived from the appearance of the frequency spectrum
graphic, which resembles the teeth of a comb.
comping A process where multiple recording takes are combined into a single composite
take. See also take.
compressor An effect that restricts the dynamic range of an audio signal. Compare
expander.
Content Link mode A mode useful for situations where multiple MIDI regions are
horizontally aligned along a single track, and you’re 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. If you want to view the contents of each MIDI region
(selected or not) in the Piano Roll Editor as the project plays, you need to activate Content
Catch mode. See also Link button.
control bar A collection of buttons located at the top of the main window, giving you easy
access to some of the most frequently used inspectors, editors, and other areas of Logic
Pro. You can customize the control bar to meet your individual needs. In earlier versions of
Logic Pro, the control bar was called the Transport bar.
controller A MIDI data type that controls a particular parameter, such as volume or pan, or
sustain. The type of command is encoded in the first data byte, while the value being sent
or received is encoded in the second data byte.
