1000 Glossary
Autopunch function Autopunch refers to an automatic entry and exit of record mode
at predefined positions. Autopunch mode is most commonly used to re-record a badly
played section of an otherwise flawless recording. The advantage is that you can
concentrate on playing, not the mechanics of driving Logic Express. Autopunch is
activated by clicking the Autopunch button in the Transport bar.
automation Automation is the ability to record, edit, and play back the movements of
all knobs, controls, and buttons, including: volume faders, pan, EQ, and aux send
controls, plus most effect and instrument plug-in parameters.
aux channel (strip) Aux channels are found in the Mixer (and to the left of the Arrange
window), and can be used as send/returns (buses) and sub-group controls.
Balance control Rotary knob directly above the Level fader of stereo channels. It
controls the relative level of the left and right signals at their outputs.
bar In musical notation, a bar is a measure that contains a specified number of beats,
and establishes the rhythmic structure of a musical piece.
Bar ruler Ruler found at the top of the Arrange, Piano Roll, Hyper, and Score windows.
It displays musical time units, including: bars, measures, beats, and beat divisions. It is
used to set and display the project position, the cycle and autopunch locators. Also see
playhead, Cycle, and Autopunch.
batch tagging The process of simultaneously tagging (marking) several audio files in
the Apple Loops Utility.
bass A musical instrument. The term also refers to low frequency sounds or
components within a sound. See frequency.
beat A musical time interval: “The beat is the regular rhythmic pulse in a composition
that people tap their feet to.” Usually a quarter note.
Beat Mapping track Global track used to analyze audio or MIDI regions, and create
tempo events based on note or transient events in these regions. This allows you to
more easily synchronize existing free recordings (those made without a metronome
click) in other projects.
beats per minute See bpm.
Bezier curve A curve created from a line that contains two points. These points affect
the line, allowing it to be pulled into a curve. In a computer application, Bezier curves
are created by moving handles at these two points, thus adjusting the curve shape.
Named after Pierre Bezier, who discovered the mathematical formula for these curves.
In Logic Express, Bezier curves are used to adjust automation curves, for example.
