MPX 200
ROTARY
Rotary speaker cabinets were originally designed to pro-
vide 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. As the spinning elements
change speed, the sound generated is truly magical. The
swirling, spacious effect is hard to describe, but is instantly
recognizable.
The rotary effect is a detailed simulation of a Leslie-style
cabinet. The input signal is split into high and low frequen-
cy bands. The rotation effect is created by a synchronized
combination of pitch shifting, tremolo and panning. Like
the physical model, the high (horn) and low (drum) fre-
quencies are "spun" in opposite directions. Horn and
drum speeds are independent, and are designed with
acceleration and deceleration characteristics to simulate
the inertia of the original mechanical elements.
A virtual requirement for any organ sound, the rotary pro-
grams also sound great with guitar and electric piano
rhythm parts. In fact, they are great alternatives to chorus
and tremolo effects for any sound source.
All of these programs should be used with Mix set to fully
Wet to achieve the full effect.
