Flex tool A tool that gives you quick access to the basic flex editing functionality, without
having to turn on Flex view in the Tracks area. See also Flex view.
Flex view A Tracks area view that allows you to edit the timing and pitch of audio material.
folder In Logic Pro, a container for regions in the Tracks area. A folder can contain other
folders or regions, much like a folder in the Finder can contain other folders or files. You
can imagine a folder as a project within a project. The inside of a folder looks just like the
Tracks area.
folder stack A type of Track Stack that lets you combine multiple tracks and control
them as one unit, without changing the audio routing of the individual subtracks. When
you create a folder stack, the channel strip assigned to the main track is called the stack
master. Using the main track or the stack master channel strip, you can mute, solo, and
adjust the volume level for the folder stack. See also Track Stack.
Format button A button on audio channel strips from which you choose the input format
of the channel strip. Click and hold this button to access the Format pop-up menu.
frame A unit of time. A second in the SMPTE standard is divided into frames that
correspond to a single still image in a video file or on video tape.
Freeze function A process that performs individual offline bounces for each frozen track,
saving almost 100 percent of the processing power used for software instruments and
effect plug-ins. All track plug-ins (including software instrument plug-ins, if applicable,
along with all related automation data) are rendered into a freeze file.
frequency A measure of the vibration of a sound signal over time, expressed in cycles per
second, or hertz (Hz). Frequency corresponds to what users hear as pitch (the highness or
lowness of a musical tone).
global tracks Tracks you can use to view, create, and edit markers, tempo events, and key
changes, as well as perform beat mapping and other operations. Global tracks are available
at the top of all linear editing windows.
Glue tool A tool used to merge regions or events by selecting and clicking them.
GM Abbreviation for General MIDI. A standard for MIDI sound modules specifying a
uniform set of instrument sounds, a standard key assignment for drum and percussion
sounds, 16-part multitimbral performance and at least 24-voice polyphony. A musical
sequence generated by a GMinstrument should play correctly on any other GMsynthesizer
or sound module.
grid An element of the Tracks area and some editors represented by vertical lines that
indicate the positions of measures, beats, and sub-beats.
Groups inspector A Logic Pro inspector used to define which controls can be edited for an
entire channel strip group at the same time, including automation, volume, pan, and sends.
GS An extended General Mstandard, developed by Roland Inc.
headroom A specified range (safety margin, measured in decibels) between the actual
audio level and the maximum permitted level (0 dBfs) that allows for unexpected signal
peaks. In the Score Editor, headroom is the margin of white space above the top staff.
