30. Reverb & Gate
This effect combines a reverb program with a gate program,
making it possibie to output only a segment of a ionger reverb
sound.
-(TIME)
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.
NOTE; This effect can also be triggered by a footswitch
plugged into the rear-panel MEM./TRG. FOOT SW
jack if the front-panel TRIGGER button LED is lit
(press the TRIGGER utton to activate or de-activate
thei footswitch trigger function).
Reverb Time (REV TIME): 0.3 — 99 seconds
The length of time it takes for the level of reverberation at 1
kHz to decrease by 60 dB.
High Frequency Reverb Time Ratio (HIGH): x0.1 — xO.1
This parameter allows alteration of the high-frequency
reverb time in reiation to the overall reverb 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 —1000 Hz
Permits roiiing 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 roiiing 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 trig­
ger opening of the gate. At 100 only high-level input signáis
will trigger the gate, whiie at 1 even the siightest input signai
wiii trigger the gate.
Hold Time (HOLD): 1 — 30,000 milliseconds
This parameter sets the amount of time the gate is “open,”
aiiowing the reverb sound to come through.
31. Pitch A
This program can actually change the pitch of an input signal
over a 2-octave range. The shifted pitch can be combined with
the direct sound (by an appropriate setting of the BALANCE
parameter) to create automatic harmonies.
Pitch Shift (PITCH): -12 — +12
Sets the degree of pitch change in semitone steps. +12 cor­
responds to an output pitch one octave higher than the input
pitch, and -12 produces an output pitch one octave lower
than the input pitch. An external MIDI keyboard can even be
used to select the desired degree of pitch shift.
Fine Tuning (FINE): -100 — +100
Permits extremely fine pitch adjustment in one-cent steps.
Delay Time (DELAY): 0.1 — 400 milliseconds
Sets the delay between the direct sound (input signal) and
the pitch-shifted output signal.
Feedback Gain (F.B. GAIN): 0 — 99%
When this parameter is set to 0, only a single pitch-shifted
sound is produced after the DELAY time has elapsed. As the
value of this parameter is increased, however, more and
more delayed repeats are produced, each pitch-shifted up
or down from the previous repeat according to the setting of
the PITCH parameter.
