46. Reverb & Gate
This effect combines a reverb program with a gate program,
making it possible to output only a segment of a longer reverb
sound.
Reverb Time (REV TIME): 0.3 — 99 seconds
The length of time it takes for the level of reverberation
kHz to decrease by 60 dB.
at 1
High Frequency Reverb Time Ratio (HIGH): xO.1
—
xl.O
This parameter allows alteration of the high-frequency
reverb time in reiation to the overail reverb time.
(TIME!
initial Delay (DELAY): 0.1—50 milliseconds
This parameter represents the delay between the direct
sound of an instrument and the first of the many reflections
that together form reverberation.
High-pass Filter (HPF): THRU, 32 Hz — WOO Hz
Permits rolling off the the low-frequency content of the
reverb signal below the set frequency. The HPF is OFF
when set to THRU.
Low-pass Filter (LPF): 1 kHz— 11 kHz, THRU
Permits rolling off the high-frequency content of the reverb
signal above the set frequency. The LPF is OFF when set to
THRU.
Trigger Level (TRG. LEVEL): 1 — 100
Determines the amplitude of the input signal required to
trigger opening of the gate. At 100% only high-level input
signals will trigger the gate, while at 0% even the slightest
input signal will trigger the gate.
Hold Time (HOLD): 1
—
30,000 milliseconds
This parameter sets the amount of time the gate is “open,”
allowing the reverb sound to come through.
Release Time (RELEASE): 5
—
32,000 milliseconds
This parameter determines the time it takes for the gate to
close completely after the HOLD time has elapsed.
MIDI Trigger (MIDI TRG.): OFF, ON
When ON, a KEY ON EVENT message from a MIDI key­
board can be used to trigger the effect.
