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 Express 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 Express. The computer CPU natively calculates the effects and instruments. Native
also refers to the internal Logic Express plug-in format, which differs from the Audio
Unit format. Logic Express native plug-ins only work in Logic Express.
normalize This function applies the current Parameter box settings to the selected
MIDI events (by altering the actual events themselves), and clears existing parameter
settings. When it comes to audio, a different Normalize function raises the volume of a
recorded audio file to the maximum digital level, without altering the dynamic content.
notch filter This filter type cuts the frequency band directly surrounding the cutoff
frequency, allowing all other frequencies to pass.
