LESLIE
LESLIE EFFECT is the simulated sound of rotating speakers.
If you connect the real Leslie speakers to this keyboard, it controls those (speakers)
WHAT IS THE LESLIE EFFECT?
In the Leslie speakers, generally, an amplifier and two rotors are
incorporated, i.e. the “Horn Rotor” responsible for the treble and
the “Bass Rotor” for the bass.
Each rotor has a speaker or speakers and a motor for controlling
speed to give the unique tremolo sound gained by the Doppler
effect.
There are also models as have not only the rotors but stationary
speakers - switchable.
The circuit to send the sound to the rotor is called “Rotary
Channel” and that to the stationary speaker is called “Stationary
Channel”.
The built-in Leslie Effect simulates them and you can get the best
effect when connected stereophonic.
[ON] BUTTON
If you touch this button, the LED will light, and the rotor starts turning. Also the
voice is heard thru the rotary channel.
[FAST] BUTTON
This switches the speed of the rotor in two steps. It switches every time you touch
it. When the LED is ON, it is FAST, and when the LED is off, it is SLOW.
[BRAKE] BUTTON
This button sets the action when the [ON] button is OFF.
When the LED is ON, it is in BRAKE mode (= The speed gradually slows down
and stops.) and if the LED is OFF, it is THROUGH. (= The Leslie effect is by-
passed and the voice comes out of the stationary channel.)
NOTE: You can not to control the Break or Through on external Leslie Speakers.
NOTE: You can fine-set the LESLIE effect i.e. speeds. (P. 66)
