These settings allow you to select the desired type of reverb, and its characteristics.
Reverb Parameters
Parameter Value Description
Reverb
Type
0 (OFF),
1 (REVERB),
2 (SRV ROOM),
3 (SRV HALL),
4 (SRV PLATE),
5 (GM2 REVERB)
Type of reverb
0 (OFF): Reverb is not used.
1 (REVERB): Normal reverb
2 (SRV ROOM): This simulates typical room
acoustic reflections.
3 (SRV HALL): This simulates typical concert
hall acoustic reflections.
4 (SRV PLATE): This simulates a reverb
plate, a popular type of artificial reverb unit
that derives its sound from the vibration of a
metallic plate.
5 (GM2 REVERB): GM2 Reverb
01: REVERB
Type
ROOM1,
ROOM2,
STAGE1,
STAGE2, HALL1,
HALL2, DELAY,
PAN-DELAY
Type of reverb/delay
ROOM1: short reverb with high density
ROOM2: short reverb with low density
STAGE1: reverb with greater late reverber-
ation
STAGE2: reverb with strong early reflections
HALL1: very clear-sounding reverb
HALL2: rich reverb
DELAY: conventional delay effect
PAN-DELAY: delay effect with echoes that
pan left and right
Time 0–127
Time length of reverberation
(Type: ROOM1–HALL2)
Delay time
(Type: DELAY, PAN-DELAY)
HF Damp
200–8000 Hz,
BYPASS
Adjusts the frequency above which the high-fre-
quency content of the reverb sound will be cut, or
“damped.” If you do not want to cut the high fre-
quencies, set this parameter to BYPASS.
Delay
Feedback
0–127
Adjusts the amount of delay feedback when
the Type setting is DELAY or PAN-DELAY.
Amount of delay sound returned to the input
(this setting is valid only if Type is DELAY or
PAN-DELAY)
02: SRV ROOM
03: SRV HALL
04: SRV PLATE
Pre
Delay
0.0–100.0 ms
Adjusts the delay time from the direct sound until
the reverb sound is heard.
Time 0–127 Time length of reverberation
Size 1–8 Size of the simulated room or hall
High Cut
160 Hz–12.5
kHz, BYPASS
Adjusts the frequency above which the high-
frequency content of the reverb will be re-
duced. If you do not want to reduce the high
frequencies, set this parameter to BYPASS.
Density 0–127 Density of reverb
Diffusion 0–127
Adjusts the change in the density of the reverb over
time. The higher the value, the more the density in-
creases with time. (The effect of this setting is most
pronounced with long reverb times.)
LF Damp
Freq
50–4000 Hz
Adjusts the frequency below which the low-fre-
quency content of the reverb sound will be re-
duced, or “damped.”
LF Damp
Gain
-36–0 dB
Adjusts the amount of damping applied to the
frequency range selected with LF Damp. With
a setting of “0,” there will be no reduction of
the reverb’s low-frequency content.
HF Damp
Freq 4000 Hz–12.5
kHz
Adjusts the frequency above which the high-
frequency content of the reverb sound will be
reduced, or “damped.”
HF Damp
Gain
-36–0 dB
Adjusts the amount of damping applied to the
frequency range selected with HF Damp. With
a setting of “0,” there will be no reduction of
the reverb’s high-frequency content.
Parameter Value Description
05: GM2 REVERB
Character 0–7
Type of reverb
0–5: reverb
6, 7: delay
Pre-LPF 0–7
Cuts the high frequency range of the sound
coming into the reverb.
Higher values will cut more of the high fre-
quencies.
Level 0–127 Output level of reverberation
Time 0–127 Time length of reverberation
Delay
Feedback
0–127
Adjusts the amount of the delay sound that is
fed back into the effect when the Reverb Char-
acter setting is 6 or 7.
