702 Glossary
Parameters area Area at the left edge of the Arrange window and editors, containing
the Parameter boxes, Toolbox, and channel strip (Arrange window) of the selected
track.
peak 1) The highest level in an audio signal 2) portions of a digital audio signal that
exceed 0 dB, resulting in clipping. You can use Logic’s level meter facilities to locate
peaks and remove or avoid clipping. The Search Peak command in the Sample Editor’s
Functions menu searches for the sample bit with the greatest amplitude value in the
currently selected Audio Region.
Pencil tool Tool used to create empty MIDI Regions in the Arrange window. It can also
be used to add Audio Regions to the Arrange window, when used in conjunction with
the Shift key. In the Sample Editor, the Pencil can be used to draw out transient signal
spikes (pops and clicks) in signals.
pink noise A harmonic noise type that contains more energy in the lower frequency
range.
pitch The perceived highness or lowness of a musical sound. Corresponds to the
frequency of the sound wave.
pitch bend message MIDI message transmitted by a keyboard’s pitch bend wheel.
playback Playing an Audio or MIDI Region or an entire arrangement, allowing you to
hear it.
plug-in Software application that enhances the functionality of the main program (in
this case, Logic). Logic’s plug-ins are typically software instruments or effects.
Plug-in window A window that launches when a plug-in is inserted, or the Insert/
Instrument slot is double-clicked. Allows you to interact with the plug-in parameters.
Pointer tool The default Toolbox tool. Used to select and/or edit Regions, events,
menu, or interface items and more in Logic.
position indicator Units: bars, beats, sub-divisions (often written simply as divisions in
this manual) and ticks.
post fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Post fader means positioned after the fader in the signal flow, with the level of a
signal going to the Send changing along with the fader movements.
pre fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Pre fader means positioned before the fader in the signal flow, so the level of a
signal routed pre fader to a Send remains constant, regardless of any fader movements.
Preferences window A window that is accessed via the Logic > Preferences menu. All
Logic preferences can be set in this window.
