● 0130: Compressor

Flattens out high levels and boosts low levels, smoothing out fluctuations in

volume.

Sets the speed at which

compression starts

5 High Gain 0-30 -15 - +15 dB Gain of the high frequency range

6 Level 0-127 0-127 Output level

● 0131: Limiter

Compresses signals that exceed a specified volume level, preventing distortion

from occurring.

No Parameter Value Description

1 Release 0-127 0-127

Adjusts the time after the signal

volume falls below the Threshold

Level until compression is no

longer applied.

2 Threshold #1 0-127 0-127

Adjusts the volume at which

compression begins

3 Ratio #2 0-3

1.5:1, 2:1, 4:1,

100:1

Compression ratio

4 Post Gain 0-18 0 - +18 dB Adjusts the output gain.

5 Low Gain 0-30 -15 - +15 dB Gain of the low frequency range

6 High Gain 0-30 -15 - +15 dB Gain of the high frequency range

7 Level 0-127 0-127 Output level

● 0142: Stereo Chorus

This is a stereo chorus. A filter is provided so that you can adjust the timbre of

the chorus sound.

No Parameter Value Description

1 Filter Type 0-2 Off, Lpf, Hpf

Type of filter

Off: No filter is used

Lpf: Cuts the frequency range

above the Cutoff Freq

Hpf: Cuts the frequency range

below the Cutoff Freq

2 Cutoff Freq 0-16 200-8000 Hz Basic frequency of the filter

3 Pre Delay 0-125 0.0-100.0 ms

Adjusts the delay time from the

direct sound until the chorus

sound is heard.

4 Rate Mode 0-1 Hz, note

When this is set to “note,” the

effect is synchronized with the

tempo.

5 Rate #1 1-127 0.05-10.00 Hz Frequency of modulation (Hz)

6 Rate 0-21 note Frequency of modulation (note)

7 Depth #2 0-127 0-127 Depth of modulation

8 Phase 0-90 0-180 deg Spatial spread of the sound

9 Low Gain 0-30 -15 - +15 dB Gain of the low range

10 High Gain 0-30 -15 - +15 dB Gain of the high range

11 Balance 0-100

D100:0W -

D0:100W

Volume balance between the direct

sound (D) and the chorus sound

(W)

12 Level 0-127 0-127 Output Level

● 0140: Hexa Chorus

Uses a six-phase chorus (six layers of chorused sound) to give richness and

spatial spread to the sound.

No Parameter Value Description

1 Pre Delay 0-125 0.0-100.0 ms

Adjusts the delay time from the

direct sound until the chorus

sound is heard.

2 Rate Mode 0-1 Hz, note

When this is set to “note,” the

effect is synchronized with the

tempo.

3 Rate #1 1-127 0.05-10.00 Hz Frequency of modulation (Hz)

4 Rate 0-21 note Frequency of modulation (note)

5 Depth #2 0-127 0-127 Depth of modulation

6 Pre Delay Deviation 0-20 0-20

Adjusts the differences in Pre

Delay between each chorus

sound.

7 Depth Deviation 0-40 -20 - +20

Adjusts the difference in

modulation depth between each

chorus sound.

8 Pan Deviation 0-20 0-20

Adjusts the difference in stereo

location between each chorus

sound. 0: All chorus sounds will be

in the center. 20: Each chorus

sound will be spaced at 60 degree

intervals relative to the center.

9 Balance 0-100

D100:0W -

D0:100W

Volume balance between the direct

sound (D) and the chorus sound

(W)

10 Level 0-127 0-127 Output Level

● 0141: Tremolo Chorus

This is a chorus effect with added Tremolo (cyclic modulation of volume).

No Parameter Value Description

1 Pre Delay 0-125 0.0-100.0 ms

Adjusts the delay time from the

direct sound until the chorus

sound is heard.

2 Chorus Rate Mode 0-1 Hz, note

When this is set to “note,” the

effect is synchronized with the

tempo.

3 Chorus Rate 1-127 0.05-10.00 Hz

chorus effect (Hz)

4 Chorus Rate 0-21 note

Modulation frequency of the

chorus effect (note)
