ed signal being fed back into the input, cre-
ating feedback. Higher amounts add more
resonance to the effect signal.
Tremolo and Panner create rhythmic
changes in signal amplitude. Tremolo
affects both channel’s amplitude simultane-
ously, while the Panner affects the ampli-
tude of each channel in an alternating
manner.
Tremolo/Pan Controls
Knob 1: Speed
Controls the modulation rate of the
Tremolo/Panner.
Knob 2: Depth
Controls the intensity of the volume ampli-
tude change.
Knob 3: Phase
Controls whether the amplitude change
occurs in both channels simultaneously
(Tremolo) or alternates between channels
(Panner).
Rotary speaker cabinets were designed to
provide a majestic vibrato/choir effect for
electronic theater and church organs. The
most well known rotary speaker is the
Leslie™ Model 122, which has two count-
er-rotating elements: a high-frequency horn
and a low-frequency rotor with slow and
fast speeds. The sound generated as the
spinning elements change speed is truly
magical. The swirling, spacious effect is
difficult to describe – but clearly recogniza-
ble.
The Rotary effect is modeled 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 physical cabinet, the high
(horn) and low (rotor) frequencies are
“spun” in opposite directions. Horn and
rotor speeds are independent, and
designed with acceleration and decelera-
tion characteristics to simulate the inertia
of the original mechanical elements.
A virtual requirement for organ music,
Rotary also sounds remarkable with guitar
and electric piano rhythm parts. In fact,
these programs are great alternatives to
the Chorus and Tremolo effects for any
sound source.
Rotary Controls
Knob 1: Speed
Controls the modulation rate of both rotary
speakers. The lower frequencies rotate at
a slower speed than the high frequencies.
Knob 2: Doppler
Increases or decreases the Doppler pitch
effect that is created by the physics of a
rotating speaker.
Knob 3: Stereo Spread
Increases or decreases the stereo imaging
of the Rotary effect.
Vibrato is obtained by smoothly varying
the pitch of the signal just sharp and flat of
the original at a determined rate.
