Using the COSM Rotary Speaker Effect (Rotary Sound)

Rotary Sound is an effect which adds the modulation that is produced when organ voices are used with a rotary speaker. On most rotary speakers, the high-frequency speaker and low-frequency speaker rotate at different speeds. The VK-8 can simulate this type of complex modulation.

[SLOW/FAST] button

Switches the speed of the rotary speaker. FAST and SLOW will alternate each time you press the [SLOW/FAST] button.

FAST rotation is selected when the indicator blinks rapidly. SLOW rotation is selected when the indicator blinks slowly. When you change between slow/fast, the speed of rotation will change gradually.

[BRAKE] button

This button temporarily halts the rotation of the rotary sound.

Button

Explanation

The speed of rotation will gradually slow down and then stop.

Lit (ON)

From a stopped condition, the rotation will gradually be- come faster.

Dark (OFF)

ROTARY [ON] button

The rotary speaker effect can be switched off.

Button

Explanation

The rotary speaker will be applied.

Lit (ON)

The rotary speaker effect will not be applied.

Dark (OFF)

The VK-8 uses an effect algorithm based on COSM technology, and is able to faithfully reproduce the modulation of an actual rotary speaker and the irregularities of its rotation. You can also make sophisticated settings, such as the characteristics of the amplifier (p. 33), the resonance of the speaker cabinet, and the distance of the microphone which picks up the sound of the rotary speaker (p. 50).

You can use a foot switch or D Beam controller to switch the rotary speaker between fast and slow. For details, refer to “Using the D BEAM Controller to Produce Common Organ Effects” (p. 34) and “Assigning a Function to the Control Pedal” (p. 40).

When a rotary speaker is connected to the ROTARY TONE CABINET jack on the rear panel, the rotary effect is not applied, and the [SLOW/ FAST] button, [BRAKE] button, and ROTARY SOUND [ON] button function as follows.

ROTARY SOUND [ON]

Button

Disabled when a rotary

speaker is connected.

[SLOW/FAST] Button

Changes the speed of the

connected rotary speaker.

[BRAKE] Button

Temporarily stops the rotation

of the connected rotary

speaker.
