1026 Glossary
transposition 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 Express 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).
VU meter Abbreviation for Volume Unit meter. An analog meter used to monitor audio
levels.
WAV, WAVE The primary audio file format used by Windows-compatible computers. In
Logic Express, all recorded and bounced WAV files are in Broadcast Wave format, which
includes high-resolution timestamp information that stores positional information. This
makes it easy to align these files in other audio and video applications.
waveform A visual representation of an audio signal. Waveform graphics run from left
to right, and are centered on a horizontal line. Louder portions of the waveform
(amplitude peaks) are indicated as taller spikes or higher curves in the waveform.
wet/dry mix Refers to the ratio of a signal that effects have been added to (wet), and
the original, unprocessed signal (dry).
