Aerosol is a true stereo chorus/

flanger with dual rate, depth and
resonance controls. It can pro-
duce very deep resonant flange
sweeps, subtle multi-vibrato, ste-
reo image enhancement and a
wide variety of other chorus and
flanger-like effects.

A pair of single-tap modulated

delays is each modulated by a
separate LFO. Pulse Width allows
independent adjustment of left and
right LFOs from full left to full right
skew. (At 0, the sinewave becomes
a sawtooth with a fast rise and
slow fall.) Depth controls provide
adjustment of modulated depth
from 0-100%.

This effect simulates a Leslie

speaker with one pair of stereo
mics on the rotating low-frequency
drum, and another pair on the ro-
tating high-frequency horn. Bal sets
the relative mix of Drum and Horn
mics. Width controls the stereo
spread of both pairs of mics. Rate
and Depth 1 control the speed and
depth of the rotating low-frequency
drum. Rate 2 and Depth 2 control
the speed and depth of the rotating
high-frequency horn. The preset,
Rotary Cab, is set up so that A/B
switches the speed from fast to
slow. Different A and B rates are
used to simulate the inertia of the
mechanical system.
