Of the two delays, feedback is applied only to one
(delay B). This means that the timing of the second and
subsequent echoes produced by both delays will be

19, 20: Chorus
The chorus effects use an LFO (low frequency oscilla-
tor) to modulate the delay time, adding depth to the
sound. This delay produces a slight variance in pitch,
and when it is combined with the original signal, an
effect as though multiple instruments were playing in
unison is produced.

Set the length of Delay A.
Set the length of Delay B.
Set the amount of feedback; i.e.,
the amount of the Delay B signal
that will be returned to the input
of the delay. Higher settings will
produce a greater number of
delay repeats, and it will take
longer for the echoes to die
away. Negative settings will
invert the phase of the feedback,
causing the echoes to have a
harder tone quality, and less of a
hollow feeling.
Set the amount of boost or cut
that the shelving type equalizer
will apply to the region below 1
kHz.
Set the amount of boost or cut
that the shelving type equalizer
will apply to the region above 1
kHz.
Set the balance between the
direct sound (DRY) and the
sound processed by the effect
(FX). With a setting of DRY, the
effect will be turned off. With a
setting of FX, only the echoes
will be heard. Other settings set
the proportion of the direct
sound and effect sound.
