Yamaha REX50 - Manual (Page 12)

These 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.
/ 13. REVERSE GATE /
This effect produces a dynamic "slapback" sound,
similar to a tape recording being played backwards.

/ 6. GATE REVERB /
Early Reflection Pattern (TYPE):
HALL/RANDOM/REVERSE/PLATE
The TYPE parameter selects one of four different pat­
terns of early reflections. HALL produces a typical
grouping of early reflections that would occur in a
performing environment such as a hall. RANDOM
produces an irregular series of reflections that could
not occur naturally. PLATE produces a typical group­
ing of reflections that would occur in a plate reverb
unit. REVERSE generates a series of reflections that
increase in level — like the effect produced by play­
ing a recorded reverberation sound backwards.
Room Size (ROOM SIZE): 0.1 - 20.0
This parameter sets the time intervals between the
early reflections — a feature of natural early reflec­
tions which is directly proportional to the size of the
room.
Liveness (LIVENESS): 0 -10
"Liveness" refers to the rate at which the reflected
sounds fade. An acoustically "dead" room is simu­
lated by setting this parameter to zero. Increasing
the value of this parameter creates an increasingly
"live" sound, simulating an increasing area of reflec­
tive surfaces in the room.
Delay (DELAY): 0.1 - 400.0 ms
The time delay between the direct sound of the in­
strument and the first of the early reflections.
Low-pass Filter (LPF): 1 kHz - 11 kHz, THRU
Permits rolling off the high-frequency content of the
early reflection signal above the set frequency. The
LPF is OFF when set to THRU.
