Glossary 999
tempo The playback speed of a piece of music, measured in beats per minute.
Logic Pro 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 MIDI sequencer. In Logic Pro, this is 1/
3840th of a note. Logic Pro can go down to single sample accuracy (at sufficient zoom
levels) for edits and positioning, but the MIDI protocol is not fast enough to support
this.
time code A format (and signal) for assigning a unique, sequential time unit to each
frame of video or project position. The SMPTE time code format, for example, is
measured in hours : minutes : seconds : frames and subframes.
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).
Toolbar The top of the Arrange window features the Toobar, which is used to access or
hide certain onscreen areas, such as the Media or Lists area or Inspector. It also contains
a number of buttons for key functions, such as Locking/Unlocking SMPTE positions. You
may freely customize the Toolbar to meet your needs.
Tool menu Available in the local menu bar of a window, containing tools for editing,
zooming, cropping, and otherwise manipulating items in the window.
track A horizontal row in the Arrange that contains either audio or MIDI regions that
can be played back over time. Each track has a specified destination (a channel strip)
that data is routed to. Logic Pro allows hundreds of tracks to be used in a project.
track arming See record enable.
track list Situated to the left of the Arrange. Displays the channel strips assigned to
various tracks as well as Track Solo, Mute, and other buttons.
Track Parameter box See Object Parameter box.
Track Protect button The button featuring the lock icon, shown in the Arrange track
list, protects or unprotects tracks from further editing. Also see protected track.
