03D—Owner’s Manual
Edit buffer
—The internal RAM area that stores the current mix settings (i.e. the cur-
rent mix scene). When a mix scene is stored, the Edit Buffer data is copied to the
selected scene memory. When a mix scene is recalled, the data of the selected scene
memory is copied back to the Edit Buffer.
EFF
—Abbreviation for effect.
Emphasis
—A technique that was used to improve the noise performance of the first
generation of AD/DA converters. Although not used today, it is often provided for com-
patibility with older recordings. The emphasis technique consisted of boosting signals
above 3.5 kHz by 6 dB/octave before A/D conversion. The playback device sensed the
Emphasis flag in the digital audio signal and de-emphasised the signal after D/A con-
version.
EQ snapshot
—A set of EQ settings.
Fade time
—The time it takes a fader to move to its new position when a mix scene is
recalled. Used for cross fade.
General MIDI
—An extension to the MIDI Standard that, among other things, states
that a GM compatible tone generator must be at least 24-note polyphonic, have 16
parts, and 128 specific preset voices.
GR
—Abbreviation for gain reduction.
Initial settings
—The settings used when a device is first turned on after leaving the
factory. Also referred to as the default or factory settings.
LCD (Liquid Crystal Display)
—A type of display device that uses liquid crystal to
generate characters and graphics.
LED (Light Emitting Diode)
—A type of diode that lights up when an electric cur-
rent is applied.
Line-Level Signal
—A signal in the range from –20 dB to +20 dB. These are essen-
tially high-level signals. Most audio equipment outputs signals at line level. Contrast
with Low-Level Signal.
Low-Level Signal
—A signal in the range from –100 dB to –20 dB. Microphone and
electric guitar signals are in this range. Contrast with Line-Level Signal.
LSB (Least Significant Byte)
—
The byte of a digital word that represents the lowest
value. Contrast with MSB.
MIDI (Musical Instrument Digital Interface)
—An internationally agreed pro-
tocol that allows electronic musical instruments and audio equipment to communi-
cate.
MIDI Clock
—A clock signal transmitted as MIDI data. MIDI Clock refers to a timing
signal and Start, Continue, and Stop commands.
MIDI Device Numbers
—Identity numbers assigned to MIDI devices for transmit-
ting System Exclusive data.
MIDI Song Position Pointer
—A type of MIDI message that is used to derive posi-
tion information from a MIDI Clock signal. So no matter where you start playback in
a song, your MIDI sequencer will locate to that point and then play along in synchro-
nization.
MIDI timecode
—See MTC.
Mix scene
—A set of mixer settings at a particular point in a song. Just like a play, a
piece of music consists of various scenes, each requiring different mixer settings. Mix
scenes are stored in scene memories, and can be recalled using front panel buttons or
MIDI Program Change messages. These messages can be sent from a computer, MIDI
footswitch, keyboard, or sequencer. See also Scene memories.
