Yamaha REX50 - Manual (Page 18)

This effect combines a reverb program with a gate pro­
gram, making it possible to output only a segment of
a longer reverb sound.
/ 16. REVERB & GATE /
-(TIME)
Reverb Time (REV TIME): 0.3 - 99.0 s
The length of time it takes for the level of reverbera­
tion at 1 kHz to decrease by 60 dB.
High Frequency Reverb Time Ratio (HIGH): 0.1
1.0
This parameter allows alteration of the high-
frequency reverb time in relation to the overall reverb
time.
Initial Delay (DELAY): 0.1 — 50.0 ms
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 - 1.0 kHz
Permits rolling off 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 - 1 0 0
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 1 %
even the slightest input signal will trigger the gate.
Hold Time (HOLD): 1 - 30,000 ms
This parameter sets the amount of time the gate is
"open," allowing the reverb sound to come through.
Release Time (RELEASE): 5 — 32,000 ms
This parameter determines the time it takes for the
gate to close completely after the HOLD time has
elapsed.
MIDI Trigger (MIDI TRG.): OFF, OIM
When ON, a KEY ON EVENT message from a MIDI
keyboard can be used to trigger the effect.
/ 1 7 . PITCH CHANGE AV
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 - -H2
Sets the degree of pitch change in semitone steps.
+12 corresponds 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 - -HOP
Permits extremely fine pitch adjustment in one-cent
steps.
Delay Time (DELAY): 0.1 - 400.0 ms
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 increas­
ed, 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.
