Tremolo/Pan - Stereo (Wet Only)
Tremolo and Panner create rhythmic changes in signal amplitude. Tremolo
affects both channel’s amplitude simultaneously, while the Panner affects the ampli-
tude of each channel in an alternating manner.
Rotary - Mono In/Stereo Out (Wet Only)
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 counter-rotating elements: a high-frequency horn
and a low-frequency rotor with slow and fast speeds. The sound generated as the spin-
ning elements change speed is truly magical. The swirling, spacious effect is difficult to
describe – but clearly recognizable.
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 com-
bination 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 deceleration 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.
Vibrato - Stereo (Wet Only)
Vibrato is obtained by smoothly varying the pitch of the signal just sharp and flat of
the original at a determined rate.
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 MX400’s Pitch Shift effect is a chromatic 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 with-
out the audible sweep caused by the chorus rate.
