1000 Glossary
transform set A collection of transform operations (performed in the Transform
window) can be saved as a transform set. Saved transform sets can be quickly accessed
via the Presets menu at the top left of the Transform window. You may also import
transform sets from other projects. See entry below.
Transform window Logic Pro editor that lets you define a set of conditions and
operations that are used to select and manipulate specific MIDI events.
transient Position in an audio recording where the signal becomes a lot louder—over
a short time span (a signal spike, in other words). As this is typical for drum recordings,
transients can be used to indicate where beats occur in an audio signal.
Transport bar A field shown at the bottom of the Arrange window, used to control
recording and playback functions. The Transport bar offers Record, Pause, Play, Stop,
and Rewind/Forward buttons plus other functions. You can also open independent
Transport bar windows by choosing Window > Transport (Command-7).
transpositon Transposition is the act of changing the pitch of an audio or MIDI region
(or event) by a number of semitones.
Transposition track Global track component that shows transposition events.
treble Refers to high frequency sounds or components within a sound. See frequency.
Undo function Function which reverses the previous editing operation. The Undo
History allows multiple undo steps to be made.
unicode Fundamentally, computers just deal 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, no matter what the program,
no matter what the language.
velocity Force at which a MIDI note is struck; controlled by the second data byte of a
note event.
Velocity tool This tool, found in the Logic Pro MIDI editors, allows the velocity of
individual, or grouped, note events to be adjusted.
Video track A global track component that allows the viewing of video clips.
virtual memory Area of the hard disk used as an extension of RAM memory by the
computer. The disadvantage is its very slow access time, in comparison to physical
RAM.
Voice Separation tool You can separate polyphonic voices onto different staffs in the
Score Editor by drawing a dividing line with the Voice Separation tool (provided you
are using a polyphonic staff style).
