cable In Logic Pro, the term is used to describe the virtual cables that represent a MIDI
connection between Environment objects.
CAF Abbreviation for Core Audio Format. This file format can be used as a container for
compressed or uncompressed audio files of (almost) any size, sample rate, or bit depth.
The CAF file format can handle audio recordings of around 3 hours in length (at a
44.1 kHz sample rate—shorter at higher sample rates).
Camera tool The Camera tool is used to select, and export, sections of the Score Editor
display as PDF files.
Caps Lock Keyboard Logic Pro function that allows the use of the computer keyboard
as a real time MIDI keyboard. It is primarily intended for use while travelling with a
portable Macintosh.
Catch button The button at the top left of most windows featuring the running man
icon. Activate this button to enable horizontal scrolling during playback. This ensures
that the area of the project which surrounds the current playhead position is always
visible.
CD Audio Short for Compact Disc—Audio; a standard for stereo music CDs: 44.1 kHz
sampling rate and 16 bit depth.
cent A tuning division of a semitone. There are one hundred cents in a semitone. Many
of the Logic Pro software instruments contain a Fine parameter that allows sounds to
be tuned in cent steps.
channel strip A channel strip is a virtual representation of a channel strip on a mixing
console. Each channel strip contains a number of similar controls, which can include
some or all of the following: a Mute button, Level fader, Pan/Balance control, Input slot,
Output slot, Send slots, Insert slots, Format button. The channel strips shown to the left
of the Arrange window, and in the Mixer window, are used to process audio or MIDI
information that is routed from Arrange tracks.
channel strip setting Logic Pro allows the routing of a channel strip, including all
inserted effects or instruments (plus their settings) to be saved and recalled. This
simplifies the task of recreating complex serial effect routings between channels or
projects.
checkbox A small box. You click a checkbox to select or deselect (or turn on/off ) an
option.
Chord track One of the global tracks. Contains chord symbols that can be derived
from MIDI regions or created with the mouse. These chord symbols may also be
inserted into the score. The root note of the chords determines the transposition (pitch
shifting) of all Apple Loops, and can also affect the playback of MIDI regions.
