Glossary 1007
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 Express.
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).
Event List A list that shows all events or regions in a project. It allows you to directly
manipulate events and regions in a precise, numerical way. It also allows you to add
different types of events.
expander An effect process that increases the dynamic range of an audio signal. It is
the antithesis of the compression effect (see compressor).
export To create a version of a file, such as a Logic Express project, in a different format
that can be distributed and used by other applications.
Fade tool Tool in the Arrange area, used to create a cross-fade.
filter effect Filters are effects designed to reduce the energy of a specific frequency
within a signal. The names of the individual filters illustrate their function. As an
example: A low pass filter allows frequencies that are lower than the cutoff frequency
to pass (see cutoff frequency).
Filter button Buttons in the Event List and Mixer, that allow you to hide or show
specific event types or channel strip types.
filter slope The filter slope is the steepness, or severity, of filter attenuation (level
reduction). As examples, a filter slope of 6 dB per octave would sound much softer than
a filter slope of 12 dB per octave.
Find field In many Logic Express windows you find a field with rounded corners and a
magnifying glass to the left. This field allows you to perform text searches. As examples,
the Find fields in the Key Commands window or Loop Browser.
