Rotary
Mono In/Stereo Out (Wet Only)
Rotary speaker cabinets were designed to provide a majestic vibrato/choir effect for electronic theatre and church
organs. The most well known rotary speaker is the Leslie™ Model 122, which has two counter-rotating elements: a
high-frequency horn and a low-frequency rotor with slow and fast speeds. The sound generated as the spinning ele-
ments change speed is truly magical. The swirling, spacious effect is difficult to describe – but clearly recognizable.
The Rotary effect is modelled after a Leslie-style cabinet. The input signal is split into high and low-frequency bands.
The rotation effect is created by a synchronized combination of pitch shifting, tremolo, and panning. Like the physi-
cal cabinet, the high (horn) and low (rotor) frequencies are “spun” in opposite directions. Horn and rotor speeds are
independent, and designed with acceleration and deceleration characteristics to simulate the inertia of the original
mechanical elements. A virtual necessity for organ music, Rotary also sounds remarkable with guitar and electric piano
rhythm parts. In fact, this program is a great alternative to the Chorus and Tremolo effects for any sound source.
Pitch Shift
Stereo
This effect shifts the frequency spectrum of the input signal. Altering the pitch of a sound produces a wide range
effects - from subtle detunes to full interval shifts up or down a two octave range. The Pitch Shift effect is a chromat-
ic shifter, meaning all notes of the scale are shifted by the same interval. Pitch Shift is very useful with guitar tracks,
monophonic synth lines, or where special vocal effects are needed.
Detune
Stereo
Detune adds a slightly pitch-shifted version of the original source, thickening the sound. This creates a particularly
effective simulation of “double-tracking.” This effect is also a great alternative to the Chorus effect, adding the richness
of a chorus without the audible sweep caused by the chorus rate. It is also useful for creating a wide stereo signal
from a mono source, by setting a small detune amount up on one output and down on the other, and panning the two
outputs hard left and right.
Misc FX Parameters
Speed
Sets the speed at which the modulated effect cycles.
LFO Depth
Scales the intensity of the effect.
This control affects the output of the LFO only. It has no effect on the outputs of the individual waveforms.
