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.
