Apple Logic Pro 9 - Manual (Page 1325)

MIDI region Data container for MIDI events, shown in the Arrange area as a named
horizontal beam.
MIDI Time Code (MTC) Translation of a SMPTE time code signal into a MIDI standard
time code signal. MTC is used to synchronize Logic Pro with MIDI devices, other sequencers,
video and audio tape or hard disk machines that support MIDI Time Code. MTC determines
absolute time positions and supports start, stop, and continue messages.
mixdown A term commonly used to describe either bouncing (see bounce) or merging
of tracks (see merge).
Mixer The Mixer window displays all (or the desired) track, instrument, and MIDI channel
strips. These channels allow you to control all aspects of track output and processing,
including level, panning, effect and instrument processing, routing, and more.
Mixer layer An Environment layer that shows all channel strips in a project (except MIDI
channel strips). In general, you will not need to access this Environment layer as all mixing
duties can be performed in the Mixer window.
mixing The process of shaping the overall sound of a project by adjusting the volume
levels, pan positions, adding EQ and other effects, and using automation to dynamically
alter these and other aspects.
M-LAN A Yamaha-designed variant of the FireWire interface. It enables Yamaha digital
mixers and other devices to be directly connected to a Macintosh FireWire port (see
FireWire).
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. Many Logic Pro effects and
synthesizers contain modulators.
modulation amount The strength, or intensity, of modulation.
modulation matrix The EXS24 mkII (and some other Logic Pro instruments) contains a
grid that allows you to vary a number of target parameters, such as pitch, with a number
of modulators (modulation sources). This grid is referred to as the modulation matrix in
the EXS24 mkII.
modulation path A modulation path determines which target parameter will be affected
by a specific modulator (modulation source).
modulation wheel A MIDI controller found on most MIDI keyboards.
