MONO CHORUS
The Chorus effect is achieved by taking part of the signal and slightly delaying it,
then slightly detuning it as well. This detuning is variable, not steady, because it is
being modulated by an LFO (Low Frequency Oscillator). There are many possible
adjustments in this algorithm. Some of the more interesting and useful ones include
varying the LFO depth, varying the LFO speed, feeding a portion of the detuned
signal back into its own input (thus increasing the effect), and changing the LFO
waveform from a smooth triangle wave to a more abrupt square wave (causing the
detuning to become more pronounced).
STEREO CHORUS
In a Stereo Chorus, the signal is split into three parts: a dry signal and separate left
and right detunings. Whenever the left channel is detuned sharp, the right channel is
automatically detuned flat, and vice versa. This causes the effect to become more
pronounced and dramatic while keeping it “in tune” to the ear.
