Creating Organ Sounds

Adding Rotary Speaker Modulation

You can add the modulating sound that is typical of an organ with a rotary speaker connected.

fig.pnl-rot.eps

The most typical rotary speaker unit contained a high-frequency speaker (tweeter) and a low-frequency speaker (woofer), each of which rotated at a different speed. The VR-700 simulates the effect produced by a rotary speaker.

You can use the buttons in the rotary sound section to control the operation of the rotary speaker.

Button

Description

 

 

[ON] button

Turns on the rotary speaker effect.

 

 

 

Switches the rotational speed of the

 

rotary speaker.

[SLOW/FAST]

Press the [SLOW/FAST] button to toggle

between FAST and SLOW.

button

FAST is selected when the indicator is

 

 

blinking rapidly, and SLOW is selected

 

when the indicator is blinking slowly.

 

 

 

When you turn this on (lit), the rotational

 

speed of the speaker will slow down and

 

eventually stop completely.

[BRAKE] button

* The function mode setting “Rotary

Brake Position” lets you specify

 

 

whether the speaker will come to rest

 

at a random angle or at the same angle

 

each time when the rotation is stopped

 

completely (p. 52).

 

 

You can also use the bender lever (p. 14) or foot pedal to control the operation of the [SLOW/FAST] button and [BRAKE] button (p. 55).

Detailed settings for the rotary speaker

In Function mode you can make detailed settings for the rotary speaker (p. 53).

Speaker volume

You can specify the volumes of the tweeter and the woofer.

Volume of the tweeter:

Rotary Tweeter Level

Volume of the woofer:

Rotary Woofer Level

Rotational speed switching time

You can specify whether the rotational speed will change slowly or quickly.

The higher the value, the faster the change.

Changing from SLOW to FAST

Woofer:

Rotary Woofer Rise Time

Tweeter:

Rotary Tweeter Rise Time

Changing from FAST to SLOW

Woofer:

Rotary Woofer Rise Time

Tweeter:

Spread

You can specify the amount by which the sound will appear to be spread to left and right by the rotation of the speaker.

Woofer:

Rotary Woofer Spread

Tweeter:

Rotary Tweeter Spread

Rotational speed

You can specify the speeds of the SLOW and the FAST rotation.

SLOW rotational speed

Woofer:

Rotary Woofer Slow Speed

Tweeter:

Rotary Tweeter Slow Speed

FAST rotational speed

Woofer:

Rotary Woofer Fast Speed

Tweeter:

Rotary Tweeter Fast Speed

Distance between speaker and microphone

The distance between the speaker and the microphone will affect the depth of the modulation.

• Rotary Mic Distance

Inconsistency of the speaker’s rotation

Depending on the condition of the rotary speaker, the speaker’s rotation might not be perfectly consistent, and this can create distinctive sounds.

• Rotary Speed Randomize
