Program Descriptions Lexicon 4-2 SINGLE PROGRAMS PLA TE Plate reverb began with a large, thin sheet of metal suspended upright under tension on springs. T ransducers attached to the plate transmitted a signal that made the plate vibrate, causing sounds broadcast through it to appear to be occurring in a large, open space. The Plate programs synthes[...]

Program Descriptions MPX 550 4-3 GA TE/INV Gated reverbs were created by feeding a reverb, such as a metal plate, through an analog gate device. Decay time was set to instant, while hold time varied duration and sound. The Gate programs provide a fairly constant sound with no decay until the reverb is cut off abruptly . These programs work well on [...]

Program Descriptions Lexicon 4-4 HALL Lexicon’ s Hall programs recreate the acoustics of actual places - from grand, reverberant enclosures to small concert halls. The clean reverberation of Hall programs is designed to add spaciousness without altering source material. In addition to general instrumental and vocal applications, the Hall programs[...]

Program Descriptions MPX 550 4-5 CHAMBER Historically , recording studio chambers were oddly shaped rooms with a loudspeaker and set of microphones to collect ambience in various parts of the room. Stereo Chamber programs produce even, relatively dimensionless reverberation with little color change as sound decays. The initial diffusion is similar [...]

Program Descriptions Lexicon 4-6 AMBIENCE Ambience adds warmth, spaciousness, and depth to a performance without coloring its direct sound. It is commonly used to add a room sound to recorded music and speech. In music recording, Ambience can realistically add distance to close-mic’ed signals. Ambience programs simulate reflections from room surf[...]

Program Descriptions MPX 550 4-7 ROOM Room programs simulate actual rooms where there is a strong sense of being in a small, live place. These programs are useful on drums and percussion, and can also be applied to electric guitar tracks. Room Programs "Adjust" T ap 50 Bedroom (W alls) – 51 Tiled Room (LFBoost) – 52 Studio "C&quo[...]

Program Descriptions Lexicon 4-8 TREMOLO T remolo is a rhythmic change in loudness, commonly employed as an expressive technique by vocalists and wind instrument players. It is also one of the oldest effects, frequently used with electric guitar , electric piano, and occasionally vocals. Different tremolo effects are largely determined by the rate [...]

Program Descriptions MPX 550 4-9 ROT ARY Rotary speaker cabinets were designed to provide a majestic vibrato/choir effect for electronic theater and church organs. The most well-known rotary speaker is the Leslie™ Model 122, which has two counter-rotating elements: a high-frequency horn and a low-frequency drum with slow and fast speeds. The soun[...]

Program Descriptions Lexicon 4-10 CHORUS Chorus effects create lush, full sounds by multiplying the original audio source. T raditionally , these effects were used to fatten up tracks and to add body to guitar without coloring the original tone. Chorus effects are also often combined with plates, echoes, and other reverb effects. The stereo Chorus [...]

Program Descriptions MPX 550 4-11 FLANGE Flange effects were originally created by simultaneously playing back identical programs on two tape recorders, then using hand pressure against the flange of the tape reels to slow down first one machine, then the other . The result was a series of changing phase cancellations and reinforcements, with chara[...]

Program Descriptions Lexicon 4-12 DETUNE Detune effects create delayed and pitch-shifted versions of the original source, thickening the sound. This creates a particularly effective simulation of double-tracking. These effects are also great alternatives to Chorus effects, adding the richness of a chorus without the audible sweep caused by the chor[...]

Program Descriptions MPX 550 4-13 PITCH Altering the pitch of a sound produces a wide range of effects - from subtle detuning, to harmonies, to chords. The stereo polyphonic Pitch programs can be used to shift program material or monophonic sources within a range of one octave up to two octaves down. For pitch correction, set the Mix parameter to W[...]

Program Descriptions Lexicon 4-14 DL Y/EKO Delays and echoes repeat a sound a short time after it first occurs. The simplest (and oldest) delay effect is tape slap - a single repeat about 100ms after the original sound. T ape slap was often used on Elvis Presley’ s voice and rockabilly guitar tracks. T ape slap becomes tape echo when the output o[...]

Program Descriptions MPX 550 4-15 In all delay programs and dual programs, the unit uses the MstrDly parameter to scale delay times that are not controlled by T empo. In some programs, the "Adjust" parameter controls MstrDly . MstrDly can be set within a range of 0 to 100%. It is usually set to 100% in most presets. When MstrDly is set ma[...]

Program Descriptions Lexicon 4-18 DUAL PROGRAMS The dual programs combine Delay with Reverb, or either Delay or Reverb with Flange, Pitch, or Chorus. Four routing configurations are used in the variations of each dual program: Dual Stereo (Parallel), Cascade, Mono Split, and Dual Mono. • Flng-Dly , Pch-Dly , Chor-Dly , Dly-Rvb, Flng-Rvb, Pch-Rvb,[...]
