Apple Logic Pro 9 - Manual (Page 1327)

notch filter This filter type cuts the frequency band directly surrounding the cutoff
frequency, allowing all other frequencies to pass.
note attributes Describes functions found in the Attributes menu of the Score Editor.
These determine aspects such as the stem direction, color, enharmonic position, and
further options for the display (and printing) of note events.
note number Pitch of a MIDI note, controlled by the first data byte of a MIDI note event.
object The term is used to refer to the graphical representation of elements in the
Logic Pro Environment. These elements can be used to create and process MIDI data in
real time, and can even be used to create processing machines, such as virtual rhythm
generators or step sequencers. Examples of Environment objects include instruments,
multi-instruments, faders and arpeggiators, amongst others. The Environment Mixer layer
contains objects that process audio data.
Object Parameter box The Object Parameter box displays the properties of any selected
Environment object.
offset The playback point in a source audio file can differ from the start point (anchor)
of the file. This is known as an offset or start point offset. Offset is also used in conjunction
with video time code, where the start time of the Logic Pro project and QuickTime movie
file can be offset (different) from each other. A further use of the term is when the
amplitude of a waveform is off-axis from the center line (due to a recording error caused
by hardware). This can be rectified with the DC Offset function in the Sample Editor. See
DC Offset.
OpenTL Abbreviation for Open Track List. This file format, typically used for data exchange
with Tascam hard disk recorders, such as the MX 2424, can be imported and exported by
Logic Pro. The OpenTL file format only supports the exchange of audio data (audio regions,
inclusive of track position information). MIDI and automation data are ignored when
using the Logic Pro OpenTL export function.
option Alternative function, often in the form of a checkbox, sometimes also available
as a menu entry.
Option Modifier key, also known as the Alt key in MS Windows.
oscillator A synthesizer oscillator generates an alternating current, using a selection of
waveforms that contain different amounts of harmonics.
output channel strip Channel strip type in the Mixer that controls the output level and
pan/balance for each physical output of your audio interface.
Page view Score Editor view displaying notation as it will appear on the printed page.
