bus channel strip The bus channel type is primarily included for backward compatibility
with older Logic Express versions. The bus channel strip functions of earlier versions are
performed with aux channel strips in Logic Express 8.
bypass To deactivate a plug-in. Bypassed plug-ins do not drain system resources. In
Logic Express you can bypass a plug-in by either clicking its Bypass button in the plug-in
window or by Option-clicking the appropriate plug-in slot of a channel strip.
cable In Logic Express, 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 Express 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.
carrier In FM synthesis, the carrier is the equivalent of an analog synthesizer oscillator
that is producing a sine wave. The carrier frequency is modulated by the modulator.
Catch button The button at the top-left corner 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 that 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 Express 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 Express 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 re-creating complex serial effect routings between channels or projects.
