M

M Abbreviation for Mega or million.

MERGE To combine or unite. To Merge means to combine sequences, sounds, tracks, MIDI data, etc.

MIDI Stands for: Musical Instrument Digital Interface...MIDI is a computer language created to allow electronic musical kit to communicate. Synthesizers, sequencers, computers, rhythm machines, etc. can be interconnected through a standard interface. MIDI is an asynchronous, serial interface, which is transmitted at the rate of 31.25 KBaud or 31,250 bits per second.

MIDI CLOCK Midi clock determines the tempo or speed of the track & allows instruments interconnected via MIDI to be synchronized.... A sequencer for example can send out midi clock data...This can be received by a synth, which has an arpeggiator running...The arpeggiator can then be clocked as a slave, so that the arpeggiated sequence that it plays is in time with the tempo of the track. Also allows an external sequencer to be synced in clock time to an Internal sequencer on a keyboard for example...MIDI Clock runs at a rate of 24 pulses-per-quarter-note.

AMPLITUDE Amplitude is a term used to describe the amount of a signal. It can relate to volume in an audio signal or the amount of voltage in an electrical signal.

MIDI CONTINUOUS CONTROLLERS/MIDI CONTROLLERS Midi Continuous Controllers are designated computer code numbers which will effect the parameters of a synth sound or other item of midi kit...For Example: Volume = Controller No.7 etc. They allow continuously changing information such as pitch wheel or breath controller information to be passed over the MIDI line. Continuous controllers use large amounts of memory when recorded into a MIDI sequencer. Some standard MIDI Continuous Controller numbers are listed below:

PWH = Pitch Wheel
CHP = Pressure

1 = Modulation Wheel

2 = Breath Controller

3 = (Pressure on Rev. 1 DX7)

4 = Foot Pedal

5 = Portamento Time

6 = Data Entry

7 = Volume

8 = Balance

10 = Pan

11 = Expression Controller

16-19 = General purpose controllers 1-4 (High Res.)

64 = Sustain Switch (on/off)

65 = Portamento Switch (on/off)

66 = Sustenuto (chord hold)

67 = Soft Pedal (on/off)

69 = Hold Pedal 2 (on/off)

80-83 = General purpose controllers 5-8 (Low Res.)

91 = External Effects Depth

92 = Tremolo Depth

93 = Chorus Depth

94 = Detune

95 = Phaser Depth

96 = Data Increment

97 = Data Decrement

MTC or MIDI TIME CODE A basic form of time-code developed as a cheap alternative to SMPTE, and built into the MIDI protocol...Allows midi kit to synchronise with tape or other Master midi devices such as a sequencer...The master sends out a signal telling the slave devices the position in time that they should locate to and play, and keeps them in sync once play has started.

MODULATION The process of one audio or control voltage source influencing a sound processor or other control voltage source. Example: Slowly modulating pitch cyclically produces vibrato. Modulating a filter cyclically produces wa-wa effects.

MONITOR any device/amp & speaker/headphone combination used to listen to what you are doing in a live/rehearsal/studio situation.

MONOPHONIC Again from the Latin.... Mono, meaning single.........A Monophonic synth can only play one note at a time.... You cannot play chords on a Monophonic instrument..

MONO-TIMBREL As above, except in the case of Mono-Timbrel, only one Sound or Timbre can be played at a time, even though that sound may be able to be played with many simultaneous notes, such as playing chords.

MULTI-TRACK A way to record a complex musical piece by dividing it into simple tracks, and combining the tracks during playback... A machine that can record multiple tracks in sync.

MULTI-TIMBREL A Multi-Timbrel instrument can play many different sounds or Timbres...Typically a modern synth or module will play at least 16 different parts or sounds simultaneously...One sound for each available midi channel.
