egion Regions can be found on arrange tracks: They are rectangular beams that act as
containers for audio or MIDI data. There are three different types of regions: audio regions,
MIDI regions, and folder regions (usually referred to as folders). Also see audio region,
MIDI region, and folder.
Region Parameter box Box in the upper-left corner of the Arrange window, used to
non-destructively set the playback parameters for individual regions, including
quantization, transposition, velocity, compression, and delay. These parameters do not
alter the stored data. Rather, they affect how the events are played back.
release An envelope parameter that determines the time it takes for a signal to fall from
the sustain level to an amplitude of zero when the key is released. See envelope.
Replace mode A type of overwrite recording mode where the currently specified audio
region in the Arrange area is replaced with the incoming signal. To activate Replace mode,
click the Replace button in the Transport bar.
resonance A term generally associated with filters, particularly those of synthesizers.
Resonance emphasizes the frequency range surrounding the cutoff frequency. See cutoff
frequency.
reverb Reverb(eration) is the sound of a physical space. More specifically, the reflections
of sound waves within a space. As an example, a handclap in a cathedral will reverberate
for a long time as sound waves bounce off the stone surfaces within a very large space.
A handclap in a broom closet will hardly reverberate at all. This is because the time it
takes for the sound waves to reach the walls and bounce back to your ears is very short,
so the reverb effect will probably not even be heard.
ReWire An audio streaming and synchronization technology from Propellerhead software.
The output of ReWire applications can be routed into (and processed with) the Logic Pro
Mixer. Logic Pro can also control the transport operations of ReWire programs. Further
to these functions, Logic Pro instrument tracks can drive the software instruments of
ReWire applications.
ritardando A gradual slowdown of tempo (see tempo).
routing Generally refers to the way audio is sent through processing units. Also often
used to describe specific input and output assignments.
sample A digital recording of a sound at a particular instant in time.
Sample Editor The Logic Pro Sample Editor allows audio files to be destructively cut,
reversed, shortened, changed in gain, and processed in a number of other ways. It allows
editing of individual samples within an audio file consisting of thousands, or millions, of
samples. The Sample Editor also provides access to a number of special sample processing
tools, collectively known as the Digital Factory.
