Effects List
24: Digital Phaser
Phaser is an effect that adds a phase-shifted sound to the
original sound to create time-varying change, modulating the
sound.
25: 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.
26: Tremolo/Auto Pan
This is a stereo tremolo or auto-pan effect. Tremolo cyclically
modulates the volume to add tremolo effect to the sound. The
Auto Pan effect cyclically modulates the stereo location of the
sound.
Parameter Value Description
Shift Mode 4STAGE,
8STAGE Sets the number of stages in the
phase shift circuit (four (4STAGE)
or eight (8STAGE)).
Setting this to eight stages
(8STAGE) increases the number of
the frequency points that sound is
canceled, giving a sharper effect.
Manual 0–127 Specifies the center frequency at
which the sound is modulated.
Rate 0.05–10.0 Hz,
note Specifies the frequency of modula-
tion.
Depth 0–127 Specifies the depth of modulation.
Phase NORM, INV Sets the phase of both left and right
swelling.
NORM: The left and right phase
will be the same.
INV: The left and right phase will
be opposite.
Resonance 0–127 Specifies the amount of feedback
for the phaser.
Higher settings will give the sound
a stronger character.
Mix Level 0–127 Volume of the phase-shifted sound,
relative to the direct sound
Ps Low Freq 50–4000 Hz Frequency of the low range
Ps Low Gain -15– +15 dB Gain of the low range
Ps Hi Freq 2000–20000 Hz Frequency of the high range
Ps Hi Gain -15– +15 dB Gain of the high range

Parameter Value Description
Speed SLOW, FAST Simultaneously switch the rota-
tional 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.
Low Slow
Rate 0.05–10.0 Hz,
note Slow speed (SLOW) of the low fre-
quency rotor
Low Fast
Rate 0.05–10.0 Hz,
note Fast speed (FAST) of the low fre-
quency rotor
Low Accel-
eration 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.
Low Level 0–127 Volume of the low frequency rotor
Hi Slow
Rate 0.05–10.0 Hz,
note Slow speed (SLOW) of the high fre-
quency rotor
Hi Fast Rate 0.05–10.0 Hz,
note Fast speed (FAST) of the high fre-
quency rotor
Hi Accelera-
tion 0–15 Adjusts the time it takes the high
frequency rotor to reach the newly
selected speed when switching
from fast to slow (or slow to fast)
speed.
Hi Level 0–127 Volume of the high frequency rotor
Separation 0–127 Spatial dispersion of the sound
Ps Low Freq 50–4000 Hz Frequency of the low range
Ps Low Gain -15– +15 dB Gain of the low range
Ps Hi Freq 2000–20000 Hz Frequency of the high range
Ps Hi Gain -15– +15 dB Gain of the high range
