998 Glossary
surround Surround indicates playback systems that make use of multiple speakers. The
most common surround format is 5.1 channels (front left, front center, front right, left
surround, right surround, and an LFE, or subwoofer, channel), typically used in home
theater systems and in cinemas. Logic Pro supports all common surround formats, and
provides surround recording, plug-in, and mixing facilities.
Surround Panner Replaces the standard Pan/Balance control of channel strips, set to
Surround in the Output slot. Allows you to control the relative positioning of the
channel signal between the speakers available (in the chosen project surround format).
sustain pedal A momentary footswitch that is connected to MIDI keyboards. It
transmits MIDI controller number 64, which is recorded and played back by Logic Pro.
Swing parameter Alters the rigid timing of a quantization grid by delaying every other
note of a specified sub-division by a definable amount.
Sync button This button, found on the Transport bar, activates/deactivates external
synchronization mode.
synchronization Method of keeping several recording or playback devices time locked
with one another. In virtually all synchronized setups, there will be one master device
and one or more slave devices that derive their synchronization clock from the master.
synchronizer Central unit used to control the synchronization of several devices. In
most situations, Logic Pro will act as the master synchronizer.
synthesizer A device (hardware or software) that is used to generate sounds. The word
is derived from early attempts with mechanical and electronic machines to emulate (or
synthesize) the sounds of musical instruments, voices, birdsong, and so on. Logic Pro
features several software synthesizers, including the ES1, ES2, EFM 1, ES E, ES P, and
ES M.
SysEx Abbreviation for System Exclusive data. SysEx data forms the top tier in the
hierarchy of MIDI commands. These messages are tagged with an identification
number for each manufacturer (the SysEx manufacturer ID number). The actual
contents of these MIDI commands is left to the manufacturer. SysEx data is often used
to transfer individual (or banks of ) sound programs or system settings, or to address
individual sound generation or signal processing parameters.
takes A take, put simply, is a recording. Logic Pro allows you to create several takes,
one after the other, without leaving record mode. These takes can then be compiled
into a super take (see comping).
template A project that contains settings and preferences that you have defined.
Templates serve as a starting point for new projects (scoring tasks, audio only projects,
MIDI only projects, and so on, as your personal needs require). Any project can be used
as a template, and you can create and save multiple templates.
