Bank: Rotary

The Rotary programs are detailed simulations of 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 model, the high (horn) and low (drum) frequencies 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 effect also sounds great with guitar and electric
piano rhythm parts. In fact, it's a great alternative to chorus and tremolo effects for any sound source.
All of the programs in this Bank should be used with Mix set to fully Wet for the full effect.

Rotary speaker cabinets were originally 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 spinning elements change speed is truly magical.
The swirling, spacious effect is hard to describe, but is instantly reconizable.
