movement
of the Joystick
varies the tuning of the entire instrument
over a range of ±2 semitones. The Joy-
stick is "spring-returned"
to its middle in-
tune position, for convenient, momentary
"pitch bending" effects.
Forward-backwards
movement
Joystick varies the "rate" of the Chorus-
Phase effect (which is activated using the
Chorus-Phase Selector Switches). Speed
can be varied from a slow "Flanging"-type
effect to that of a rotating "Leslie"-type
speaker. The Joystick remains in whatever
forward-backward
position is set by the
performer.

systems:

semitones.
