marker Markers serve three purposes in Logic: They mark time-positions in the
Arrange window. They hold text notes and they delimit song settings. Markers can be
placed in the Marker track, or they can be placed in the Bar Ruler. Markers are generally
used for indicating and navigating to different song sections.
main menu bar The bar at the top of the computer screen, offering global functions
such as opening, saving, exporting or importing songs. It does not offer access to local
functions.
merge Mix, or combine, two or more MIDI events or Regions into a single Region.
metronome A part of Logic that produces a sound that taps out the beat. It can set by
click-holding the Metronome button in the Transport bar.
MIDI Abbreviation for Musical Instrument Digital Interface. Standardized,
asynchronous, serial and event-oriented interface for electronic musical instruments.
MIDI is an industry standard that allows devices such as synthesizers and computers to
communicate with each other. It controls a musical notes pitch, length, and volume,
among other characteristics.
MIDI channel A MIDI channel is a “tube” for MIDI data, which flows through MIDI ports
in channels. Up to 16 separate MIDI channels can pass through a port simultaneously.
MIDI message A message transmitted via MIDI consisting of one status byte and none,
one, two or many data bytes (with system exclusive commands). See event.
MIDI Multi mode Multi-timbral operating mode on a MIDI sound module where
different sounds can be controlled polyphonically on different MIDI channels. A Multi
mode sound module behaves like several polyphonic sound modules. General MIDI
describes a 16-part multi mode (the ability to control 16 different parts individually).
Most modern sound generators support multi mode. In Logic, multi mode sound
modules are addressed via Multi Instrument Objects.
MIDI Region Data container for MIDI events which is shown in the Arrange window as
a named horizontal beam. In earlier Logic versions MIDI Regions were called sequences.
mixing The process of shaping the overall sound of a song by adjusting the volume
levels, pan positions, adding EQ and other effects, and using automation to
dynamically alter aspects of the song.
modifier key Computer keyboard keys used in conjunction with alphabetical keys to
change functionality. Modifier keys include; Control, Shift, Option and Command.
modulation Generally, a slight, continuously varying change. Logic’s effects and
synthesizers contain a number of modulators.
modulation amount The strength, or intensity, of modulation.
