Glossary 595
song Main Logic file, containing all MIDI events and parameter settings (including
mixer automation data) plus information about the audio files to be played.
Song Settings The Song Settings, accessible from the File menu, are a collection of
program settings that are specific to the current song. These are different to the global
preferences that affect all Logic songs (see preference).
stereo Short for stereophonic sound reproduction of two different audio channels.
Compare with mono.
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.
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.
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.
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.
timing Measure of the ability to play notes at the right time. Timing can also refer to
synchronization between events, Regions and devices.
toggle To switch between two states such as on or off (applies to windows, parameter
values and so on).
Touch Tracks An Environment Object that allows MIDI Regions to be assigned to, and
triggered by, individual MIDI note events. This enables you to assign a number of
musical phrases to different MIDI keyboard keys, and trigger (or record) them in real-
time, making the process of arrangement faster and more intuitive.
track A horizontal row in the Arrange window that contains either Audio or MIDI
Regions that can be played back over time. Each track has a specified destination that
data is routed to. Logic allows hundreds of tracks to be used in a song.
Track List Situated to the left of the Arrange window’s working area. Displays the
Objects assigned to various tracks as well as the Track buttons.
