21: ROTARY
The Rotary eect 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 eect is most suitable for electric organ
Tones.

Parameter Value Explanation
Speed.#
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.
Woofer.Slow.Speed 0.05–10.00 Hz Slow speed (SLOW) of the low
frequency rotor
Woofer.Fast.Speed 0.05–10.00 Hz Fast speed (FAST) of the low
frequency rotor
Woofer.Acceleration 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.
Woofer.Level 0–127 Volume of the low frequency
rotor
Tweeter.Slow.Speed 0.05–10.00 Hz Settings of the high frequency
rotor
The parameters are the same as
for the low frequency rotor
Tweeter.Fast.Speed 0.05–10.00 Hz
Tweeter.Acceleration 0–15
Tweeter.Level 0–127
Separation 0–127 Spatial dispersion of the sound
Level.# 0–127 Output Level
22: VK ROTARY
This type provides modied response for the rotary speaker, with the low end boosted
further.
This eect features the same specications as the VK-7’s built-in rotary speaker.

Parameter Value Explanation
Speed.#
Rotational speed of the rotating speaker
SLOW Slow
FAST Fast
Brake.# OFF, ON
Switches the rotation of the
rotary speaker.
When this is turned on, the
rotation will gradually stop. When
it is turned o, the rotation will
gradually resume.
Woofer.Slow.Speed 0.05–10.00 Hz Low-speed rotation speed of the
woofer
Woofer.Fast.Speed 0.05–10.00 Hz High-speed rotation speed of
the woofer
Woofer.Trans.Up 0–127
Adjusts the rate at which the
woofer rotation speeds up when
the rotation is switched from
SLOW to FAST.
Parameter Value Explanation
Woofer.Trans.Down 0–127
Adjusts the rate at which the
woofer rotation speeds up when
the rotation is switched from
FAST to SLOW.
Woofer.Level 0–127 Volume of the woofer
Tweeter.Slow.Speed 0.05–10.00 Hz
Settings of the tweeter The
parameters are the same as for
the woofer.
Tweeter.Fast.Speed 0.05–10.00 Hz
Tweeter.Trans.Up 0–127
Tweeter.Trans.Down 0–127
Tweeter.Level 0–127
Spread 0–10
Sets the rotary speaker stereo
image. The higher the value set,
the wider the sound is spread
out.
Low.Gain -15–+15 dB Gain of the low range
High.Gain -15–+15 dB Gain of the high range
Level.# 0–127 Output Level
23: CHORUS
This is a stereo chorus. A lter is provided so that you can adjust the timbre of the
chorus sound.
