● 0143: Space D
This is a multiple chorus that applies two-phase modulation in stereo. It gives
no impression of modulation, but produces a transparent chorus effect.
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 Phase 0-90 0-180 deg Spatial spread of the sound
7 Low Gain 0-30 -15 - +15 dB Gain of the low range
8 High Gain 0-30 -15 - +15 dB Gain of the high range
9 Balance 0-100
D100:0W -
D0:100W
Volume balance between the direct
sound (D) and the chorus sound
(W)

● 0144: 3D Chorus
This applies a 3D effect to the chorus sound. The chorus sound will be
positioned 90 degrees left and 90 degrees right.
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
Modulation depth of the chorus
effect
8 Phase 0-90 0-180 deg Spatial spread of the sound
9 Output Mode 0-1
Speaker,
Phones
Adjusts the method that will be
used to hear the sound that is
output to the OUTPUT jacks. The
optimal 3D effect will be achieved if
you select Speaker when using
speakers, or Phones when using
headphones.
10 Low Gain 0-30 -15 - +15 dB Gain of the low range
11 High Gain 0-30 -15 - +15 dB Gain of the high range
12 Balance 0-100
D100:0W -
D0:100W
Volume balance between the direct
sound (D) and the chorus sound
(W)
13 Level 0-127 0-127 Output Level
● 0145: 2Band Chorus
A chorus effect that lets you apply an effect independently to the low-frequency
and high-frequency ranges.
No Parameter Value Description
1 Split Freq 0-16 200-8000 Hz
Frequency at which the low and
high ranges will be divided
2 Low Pre Delay 0-125 0.0-100.0 ms
Delay time from when the original
sound is heard to when the
low-range chorus sound is heard
3 Low Rate Mode 0-1 Hz, note
When this is set to “note,” the
effect is synchronized with the
tempo.
4 Low Rate 1-127 0.05-10.00 Hz
Rate at which the low-range chorus
sound is modulated (Hz)
5 Low Rate 0-21 note
Rate at which the low-range chorus
sound is modulated (note)
6 Low Depth #1 0-127 0-127
Modulation depth for the low-range
chorus sound
7 Low Phase 0-90 0-180 deg
Spaciousness of the low-range
chorus sound
8 High Pre Delay 0-125 0.0-100.0 ms
Delay time from when the original
sound is heard to when the
high-range chorus sound is heard
9 High Rate Mode 0-1 Hz, note
When this is set to “note,” the
effect is synchronized with the
tempo.
10 High Rate 1-127 0.05-10.00 Hz
Rate at which the low-range chorus
sound is modulated (Hz)
11 High Rate 0-21 note
Rate at which the low-range chorus
sound is modulated (note)
12 High Depth #2 0-127 0-127
Modulation depth for the
high-range chorus sound
13 High Phase 0-90 0-180 deg
Spaciousness of the high-range
chorus sound
14 Balance 0-100
D100:0W -
D0:100W
Volume balance of the original
sound (D) and chorus sound (W)
15 Level 0-127 0-127 Output volume
● 0122: Rotary
The Rotary effect simulates the sound of the rotary speakers often used with
the electric organs of the past. Since the movement of the high range and low
range rotors can be set independently, the unique type of modulation
characteristic of these speakers can be simulated quite closely. This effect is
most suitable for electric organ Patches.
No Parameter Value Description
1 Speed #1 0-1 Slow, Fast
Simultaneously switch the
rotational speed of the low
frequency rotor and high frequency
rotor. Slow: Slows down the
rotation to the Slow Rate. Fast:
Speeds up the rotation to the Fast
Rate.
2 Woofer Slow Speed 1-127 0.05-10.00 Hz
Slow speed (Slow) of the low
frequency rotor
3 Woofer Fast Speed 1-127 0.05-10.00 Hz
Fast speed (Fast) of the low
frequency rotor
4 Woofer Acceleration 0-15 0-15
Adjusts the time it takes the low
frequency rotor to reach the newly
selected speed when switching
from fast to slow (or slow to fast)
speed. Lower values will require
longer times.
5 Woofer Level 0-127 0-127 Volume of the low frequency rotor
6 Tweeter Slow Speed 1-127 0.05-10.00 Hz
7 Tweeter Fast Speed 1-127 0.05-10.00 Hz
