Glossary 641
modulation Generally, a slight, continuously varying change. Many Logic Studio
effects and synthesizers contain modulators.
modulation amount The strength, or intensity, of modulation.
modulation matrix The EXS24 mkII (and some other Logic Studio 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.
mono Short for monophonic sound reproduction. The process of mixing audio
channels into a single track, using equal amounts of the left and right audio channel
signals. Compare with stereo.
movie See video.
MP3 Abbreviation for MPEG-2 Audio Layer 3. A compressed audio file format,
frequently used to distribute audio files over the Internet.
MTC See MIDI Time Code.
multi instrument object An object in the Logic Pro Environment that represents a
multi timbral hardware or software device that reacts to MIDI. The multi instrument
object is essentially 16 instrument objects rolled into a single package. Each of these,
called sub-instrument, has a fixed MIDI channel. All sub-channels share the same MIDI
port. All other parameters can be set individually. The purpose of the multi instrument
object is to address multi-channel MIDI devices, which can receive MIDI data (and play
different sounds) on separate MIDI channels.
multi-timbral This term describes an instrument or other device that can play several
different sounds at the same time, using multiple MIDI channels. See MIDI multi mode.
multi trigger mode This term is associated with synthesizers such as the ES1. In this
mode, a synthesizer envelope is usually retriggered by each incoming note event.
mute Switch off the audio output of a channel or track. You can mute a track or
channel by clicking the Mute button in the track list or at the bottom of the channel
strip).
native Native refers to host-based processing of effects and software instruments in
Logic Pro. The computer CPU natively calculates the effects and instruments. Native
also refers to the internal Logic Pro plug-in format, which differs from the Audio Unit
format. Logic Pro native plug-ins only work in Logic Pro.
