Glossary 709

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

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’s ID number). The actual

contents of these MIDI commands is left to the manufacturer. They are used for

transferring individual or banks of sound programs and/or system settings, and for

addressing individual sound generation or signal processing parameters.

SysEx button Found in Logic’s Event List. This button enables/disables the display of

SysEx events and messages.

template Logic allows you to create and save any song as a template file, which can be

used as a basis for new projects. The Autoload Song is an example of a template file,

but you may wish to create several templates for; scoring tasks, audio only projects,

MIDI only projects and so on, as your personal needs require. Also see Autoload Song.

tempo The playback speed of a piece of music, measured in beats per minute. Logic

allows you to create and edit tempo changes in the Tempo track.

tempo change An event inserted into the Tempo track (as a node) that indicates a

change in tempo at a particular bar/beat position.

Tempo track One of the Global tracks that displays tempo changes as nodes.

tick The smallest unit of timing resolution in a sequencer. In Logic, this is 1/3840th of a

note.

time code A format (and signal) for assigning each frame of video or song position a

unique, sequential time unit. The SMPTE time code format is measured in

hours:minutes:seconds:frames and subframes.

time signature Two numerals separated by a diagonal bar that appear at the

beginning of a song. Common time signatures are 4/4 and 2/4. The first number

denotes the number of notes in a measure, or bar. The second number denotes a unit

of time for each beat. In a 2/4 signature, each bar has two beats; each beat is a quarter

note long.

time stretch Changing the length of an Audio Region without changing its pitch. In

Logic, you can do this in the Arrange window or Sample Editor with various menu

functions or key commands.
