dynamics Refers to changes in volume, or other aspects of a piece of music, over time.
editor Window for editing MIDI or audio data. Logic Pro offers the Hyper, Piano Roll,
Event List, and Score editors for MIDI event data, and the Sample Editor for audio data.
The Event List can also be used for region editing and positioning tasks.
Editor view Almost all Logic Pro plug-ins (and Audio Units) offer a graphical view of effect
and instrument parameters. The Editor view is the default, but can be accessed via the
Editor item in the View menu at the top of each plug-in window, should the Controls
view be visible.
effect A type of software algorithm that alters the sound of an audio signal in a variety
of ways. Logic Pro includes a set of EQ, dynamics, time-based, modulation, and distortion
effects in the Logic Pro native and Audio Units plug-in formats.
envelope The envelope graphically represents the variation that a sound exhibits over
time. An envelope, used as a controlling device, basically determines how a sound starts,
continues, and ends. Synthesizer envelopes usually consist of attack, decay, sustain, and
release phases.
Environment The Logic Pro Environment graphically reflects the relationships between
hardware devices outside your computer and virtual devices within your computer.
Beyond basic input and output handling, the Environment can be used to process MIDI
data in real time, and can even be used to create processing machines, such as virtual
rhythm generators and step sequencers or complex synthesizer editors.
Environment layer A page in the Environment, used to organize objects. Objects of the
same type (MIDI objects, for example) are generally placed on the same layer, making
usage easier.
Environment Mixer See Mixer layer.
EQ Shortened form of equalizer. Equalizers are used to boost or cut frequencies in an
audio signal. There are several types of EQ available in Logic Pro.
equalization See EQ.
Eraser A tool used for deleting items. Click a selected item to delete it. All other currently
selected items are also deleted.
event Individual MIDI command, such as a note on command. Continuous controller
movements (modulation wheel, for example) produce a quick succession of individual
events—each with an absolute value.
event definition Parameters used to define the event type displayed in the lanes of the
Hyper Editor (also see hyper set).
