Track Stack Track Stacks provide a convenient way to organize and control tracks, to
manage projects with high track counts, and to create and manage audio subgroups. There
are two types of Track Stacks: folder stacks and summing stacks. Both types have a main
track and one or more subtracks. See also folder stack and summing stack.
Tracks area The primary working space of Logic Pro. The Tracks area is used to record,
edit, and arrange the audio, MIDI, and Drummer regions in a project. It is also used for
recording and playback of automation. In earlier versions of Logic Pro, the Tracks area was
called the Arrange area.
transform set A collection of saved transform operations. Transform sets can be quickly
accessed via the Presets menu in the Transform window. You can also import transform
sets from other projects. See also Transform window.
Transform window An editor used to define a set of conditions and operations for
selecting and manipulating specific MIDI events.
transient The position in an audio recording where the signal becomes a lot louder over a
short time span (a signal spike, in other words). Because this behavior is typical for drum
recordings, transients can be used to indicate where beats occur in an audio signal.
transient detection A process in which audio files are analyzed for transients the first time
you enable a track for flex editing. See also flex editing.
transient marker A marker that denotes a significant point or peak in an audio file.
transport controls A set of buttons and other controls located in the center of the control
bar, used to control recording and playback functions. The transport controls include the
Record, Pause, Play, Stop, and Rewind/Forward buttons and other functions. You can also
open a floating Transport window.
transposition The process of changing the pitch of a project, a region, or individual notes
or chords by a number of semitones.
Transposition track One of the Logic Proglobal tracks. A transposition track allows you to
transpose parts of a project and view transposition events.
treble A term that refers to high-frequency sounds or components within a sound. See
also frequency.
unicode Fundamentally, computers deal only with numbers. They store letters and other
characters by assigning a number for each one. Unicode provides a unique number for
every character, no matter what the platform, program, or language.
untagged loopYou can add untagged loops or loop libraries to the Untagged Loops tab
of the Loop Browser, where you can preview untagged loops at their original tempo or at
the project tempo, batch analyze them for tempo information, remove any existing tempo
information, and synchronize the playback of untagged loops with your project.
varispeed A way of speeding up or slowing down the entire project, similar to the original
varispeed feature of tape machines. You can change both pitch and speed, or only speed
(while pitch remains constant).
velocity Refers to the force with which a MIDI note is struck. Velocity is controlled by the
second data byte of a note event.
Velocity tool A tool in the MIDI editors used to adjust the velocity of individual, or
grouped, note events.
