Reverb + Symphonic (PRESET bank)
Reverb → Symphonic (PRESET bank)

Reverb + Symphonic separately applies reverb and symphonic to the original sound, and then mixes the results.
Reverb → Symphonic applies reverb to the original sound and then applies symphonic.
Each aspect of the sound is controlled by the following effect parameters.

 REV TIME, HI.RATIO, INI.DLY, DIFF., DENSITY

 FREQ., DEPTH, MOD.DLY, WAVE

 REV/SYM, REV.BAL

 HPF, LPF

 SYNC, NOTE, TEMPO

 OUT LVL, MIX BAL.

■Basic parameters

■Fine parameters

■Basic parameters

FREQ.

0.05—40.00 Hz

Speed of modulation. Increasing this value will make the modulation repeat at a shorter interval.

DEPTH

0—100%

Modulation depth. Increasing this value will produce deeper modulation.

MOD.DLY

0.0—500.0 ms

Delay of the effect sound relative to the original sound.

WAVE

Sine, Tri

Waveform of the modulation signal. This will affect the character of the modulation. 
You can choose Sine (sine wave) or Tri (triangle wave).

REV TIME

0.3—99.0 s

Reverb time. This is expressed as the time over which reverberation at 1 kHz will decay by 60 dB.

HI.RATIO

0.1—1.0

Reverb time for the high-frequency range, expressed as a proportion of REV TIME. If this value is 
0.1 the time will be 1/10th the REV TIME; if it is 1.0 the time will be the same as the REV TIME. 
You can adjust these values to simulate the absorptiveness of the walls or ceiling. HI.RATIO is the 
decay of the high-frequency range.

INI.DLY

0.0—500.0 ms

Delay of the early reflections relative to the original sound. This also affects the delay until the 
reverberation is heard.

DIFF.

0—10

Diffusion of the sound to left and right. Increasing this value will make the reverberation more 
spaciousness.

DENSITY

0—100%

Density of the reverberation. Increasing this value will make the reverberation smoother. You can 
create unique effects by lowering this value.

MIX BAL.

0—100%

Balance between the original sound and effect sound. At a setting of 0% only the original sound 
will be output; at a setting of 100% only the effect sound will be output.

OUT LVL

0—100%

Output level after the original sound and effect sound have been mixed. 
Decrease this value if you want to lower the output. At a setting of 0% there will be no output.

HPF

Thru, 21.2 Hz—8.00 kHz

A filter that cuts the low-frequency portion of the effect. Frequency components lower than the 
frequency specified here will be cut. With a setting of Thru this filter will do nothing. This filter 
does not affect the original sound.

LPF

50.0 Hz—16.0 kHz, Thru

A filter that cuts the high-frequency portion of the effect. Frequency components above the fre-
quency specified here will be cut. With a setting of Thru this filter will do nothing. This filter does 
not affect the original sound.

REV/SYM

0—100%

(Reverb + Symphonic only) Balance between the reverb and symphonic. A setting of 0% outputs 
only the reverb; a setting of 100% outputs only the symphonic.

REV.BAL

0—100%

(Reverb → Symphonic only) Amount of symphonic. Raising this value will strengthen the sym-
phonic effect. At a setting of 0% only reverb will be heard.

SYNC

ON, OFF

Switches tempo synchronization on/off. If this is ON, the speed of modulation will synchronize to 
the tempo synchronization source specified by “TEMPO SOURCE” (page 23). The NOTE value 
will be set to the synchronized tempo value.

NOTE

*a

*a.

This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set 
according to this value and TEMPO. If SYNC is OFF, this value is ignored.

TEMPO

25—300

This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set 
according to this value and NOTE. If SYNC is OFF, this value is ignored.

No.
