Apple Logic Express 9 - Manual (Page 1281)

object The term is used to refer to the graphical representation of elements in the
Logic Express 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 Express 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 Express. 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 Express 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.
pan, pan position The placement of mono audio signals in the stereo field, by setting
different levels on both sides (see Balance).
Pan control Rotary knob (directly above the Level fader) on mono channel strips, that
determines the position of the signal in the stereo image.
Parameter box Field on the left side of Logic Express windows (or in the Inspector). It is
used to adjust the parameters of the selected track, regions, events, or objects. Also see
Inspector.
