These are all reverberation (“reverb” for short) effects. Reverb is the warm musical “ambience” you experience
when listening to music in a hall or other natural environment.
1. REVERB TIME Range: 0.3 … 30 sec.
Sets the amount of time it takes for the reverb sound to decay by 60 dB (virtually to silence).
2. DIFFUSION Range: 0 … 10
Adjusts the left-right “spread” of the reverb sound. The higher the value the greater the spread.
3. INITIAL DELAY Range: 0 … 63
The length of the initial delay before the actual reverb sound begins (in milliseconds). The higher the value the longer the
initial delay.
4. HPF CUTOFF Range: Thru, 22Hz … 8.0kHz
The cutoff frequency of the high-pass filter applied to the reverb sound. No filter is applied when set to “Thru”.
5. LPF CUTOFF Range: 1.0kHz … 18kHz, Thru
The cutoff frequency of the low-pass filter applied to the reverb sound. No filter is applied when set to “Thru”.
The chorus effects combine delay and modulation to effectively thicken and add warmth to the sound.
Flanging is a fairly pronounced effect based primarily on delay time modulation. By adjusting the various param-
eters you should be able to create an extremely broad range of sounds, from gentle shimmering to wild sweeps.
1. LFO FREQUENCY Range: 0 … 127
Sets the speed of LFO (Low Frequency Oscillator) modulation, and therefore the rate of effect variation.
2. LFO PM DEPTH Range: 0 … 127
Sets the depth of phase modulation. Higher values produce deeper modulation and therefore a more pronounced effect.

EaryRef (Early Reflections) effects are created using different groupings of “early reflections” — the first cluster of
reflections that occurs after the direct sound but before the dense reflections that are known as reverberation begin.
The GateRev (Gate Reverb) and RevrsGat (Reverse Gate) effects combine reverb with a selectable “gate”.
1. EARLY REF TYPE (EarlyRef1 & 2) Range: S-H, L-H, RDM, RVS, PLT, SPR
The “S-H” and “L-H” settings select typical groupings of early reflections that would occur in a small or large hall, respec-
tively. “RDM” (Random) produces an irregular series of reflections that could not occur naturally. “RVS” (Reverse) gener-
ates a series of reflections that increase in level — like the effect produced by playing a recorded reverberation sound
backwards. “PLT” (Plate) produces a typical grouping of reflections that would occur in a plate reverb unit, and “SPR
(Spring) simulates the early reflections of a spring type reverb unit.
1. GATE TYPE (Gaterev. & RevrsGat) Range: TYPE A, TYPE B
2. ROOM SIZE Range: 0.1 … 7.0
Sets the separation between reflections. Higher values produce greater separation between reflections, and therefore the
effect of a bigger room.
3. DIFFUSION Range: 0 … 10
Adjusts the left-right “spread” of the early reflection or gated reverb sound. The higher the value the greater the spread.
4. INITIAL DELAY Range: 0 … 63
Sets the delay time before the early reflection or gated reverb sound begins.
5. FEEDBACK LEVEL Range: –63 … 0 … +63
Determines the amount of effect-sound feedback returned to the input of the effect stage. Higher negative or positive
values produce a more extended effect.
