Using the effects of the internal sound generator
HF Damp (Reverb/Delay HF Damp)
Specifies the frequency above which the high-frequency component of the reverb sound will be cut.
Lowering this value will cause a greater portion of the high-frequency range to be cut, producing a softer-
toned reverb sound. If no cutting is desired, set this to BYPASS.
Values: 200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500, 3150, 4000, 5000, 6300, 8000
Hz, BYPASS
Feedback (Delay Feedback) 0–127
When the Type is DELAY or PAN-DELAY, this specifies the amount of delay sound that will be returned
(fed back) to the input of the delay. Raising this value will cause the delay to continue repeating for a
greater number of times.
When Reverb Type is 2 (Room), 3 (SRV Hall), or 4 (SRV Plate)
Pre Delay (Pre Delay Time) 0.0–100 ms
Specifies the amount of time that is to pass after the original sound is heard before the reverb begins to
sound.
Time (Reverb Time) 0–127
Specifies the length of time over which the reverb sound will decay.
Size 1–8
Adjusts the size of the room/hall. Higher settings will simulate a larger space.
High Cut (High Cut Frequency)
Specifies the frequency above which the high-frequency component of the final output sound will be cut.
If no cutting is desired, set this to
BYPASS .
Range: 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, 2000, 2500, 3200, 4000, 5000, 6400,
8000, 10000, 12500 Hz, BYPASS
Density (Reverb Density) 0–127
Adjusts the density of the reverb sound. Higher settings will produce a denser sound.
Diffusion (Reverb Diffusion) 0–127
Adjusts the way in which the density of the reverb sound will change over time. With higher settings of
this parameter, the sound will become denser as time passes. The effect of this parameter is easy to notice
with longer Reverb Time settings.
LF Damp Freq (LF Damp Frequency)
Specifies the frequency below which the low-frequency component of the reverb sound will be cut.
Range: 50, 64, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, 2000, 2500, 3200,
4000 Hz
LF Damp Gain -36–0 dB
Adjusts the amount of attenuation for LF Damp. With a setting of “0,” LF Damp will have no effect.
HF Damp Freq (HF Damp Frequency)
Specifies the frequency above which the high-frequency component of the reverb sound will be cut.
Range: 4000, 5000, 6400, 8000, 10000, 12500 Hz
HF Damp Gain -36–0 dB
Adjusts the amount of attenuation for HF Damp. With a setting of “0,” HF Damp will have no effect.
