Creating Organ Sounds
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.
You can also use the bender lever (p. 14) or foot pedal to
control the operation of the [SLOW/FAST] button and [BRAKE]
Adding Rotary Speaker Modulation
Button
Description
[ON] button
Turns on the rotary speaker effect.
[SLOW/FAST]
button
Switches the rotational speed of the
rotary speaker.
Press the [SLOW/FAST] button to toggle
between FAST and SLOW.
FAST is selected when the indicator is
blinking rapidly, and SLOW is selected
when the indicator is blinking slowly.
[BRAKE] button
When you turn this on (lit), the rotational
speed of the speaker will slow down and
eventually stop completely.
* 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).
Detailed settings for the rotary speaker
In Function mode you can make detailed settings for the rotary
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:
Rotary Tweeter Rise Time
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.
