shelving EQ A type of EQ that allows the frequency range above or below the specified
frequency to be increased or decreased.
side chain An alternative input signal—usually routed into an effect—used to control an
effect parameter. For example, you could use a side chained track containing a drum loop
to act as the control signal for a gate inserted on a sustained pad track, creating a rhythmic
gating effect of the pad sound.
Signature List A window (or tab) that lists all time and key signatures of a project.
Signature track A global track that shows all time and key signatures of a project.
Single Trigger mode A term associated with synthesizers such as the ES1. In this mode,
envelopes are not retriggered when tied (legato) notes are played.
Smart Control Smart Controls let you control the sound of the selected track using
a set of onscreen controls. Smart Controls can control both channel strip and plug-in
parameters, including software instruments and effects. See also screen control.
Smart TempoSmart Tempo lets you record a performance without the metronome and
have Logic Pro adapt the project tempo to match the tempo of the recording, or keep the
project tempo and flex the recording to match it. Using Smart Tempo, you can also also
create remixes using audio files and MIDI regions with different tempos that all conform
to the project tempo, or adapt the project tempo to the tempo of an imported audio file or
MIDI region.
Smart Tempo EditorIn the Smart Tempo Editor, you can view and edit Smart Tempo
analysis results including beat markers and other tempo information. After recording a
region or importing a file using Smart Tempo, you can refine the tempo analysis and correct
any tempo detection errors to define the musical intent more accurately.
SMPTE Abbreviation for Society of Motion Picture and Television Engineers. The
organization responsible for establishing a synchronization system that divides time into
hours, minutes, seconds, frames, and subframes (SMPTE timecode). SMPTE timecode is
also used for synchronizing different devices. The MIDI equivalent of SMPTE timecode is
MIDI Time Code (MTC). See also MTC.
SMPTE Time ruler Refers to the Logic Pro ruler when set to display time in SMPTE format.
The SMPTE Time ruler can display timecode if a movie is added to a project.
Snap pop-up menu A pop-up menu found in the local menu bar of linear editing windows
that determines the behavior of regions or events when edited. Lengths and cuts will snap
to the nearest possible position as determined by the value chosen in the Snap pop-up
menu.
software instrument A virtual instrument for which the sound is calculated by the
computer processor, and played via the audio interface outputs. Often colloquially called
softsynths or soft samplers. Logic Pro includes a large collection of native software
instruments to use in your projects.
software instrument channel stripLogic Pro supports the use of software-based
instruments. Software instrument plug-ins are inserted into the Instrument slot of
instrument channel strips. Software instrument recording takes place on instrument tracks
in the Tracks area. Playback of these tracks is routed via the instrument channel strip in the
Mixer.
