As with reverb, this effect is indispensable for music
production using electronic musical instruments. It is
especially widely used on synth pads such as strings
and vocal chorus, and applying a chorus effect to such
sounds will add a character of enveloping spacious-
ness. However much you may like this, it is still not a
good idea to apply chorus to all of your sounds.
Although chorus does add spaciousness to the sound,
it can also turn sound into un-expressive mush. It is up
to you, the musician, to use chorus appropriately for
the type of music that you wish to create.
19: Chorus 1 modulates the left and right channel
delays in opposite phase, causing the stereo image to
sway from side to side.
20: Chorus 2 modulates both channels with the same
phase.
For either effect, the left and right channel signals are
sent through a two-band shelving equalizer before the
chorus effect is applied.
21, 22: Quadrature Chorus
The Quadrature Chorus effect is similar to the previ-
ously-described Stereo Chorus. The difference is that
the modulation applied by the LFO to the left and
right channels is 90 degrees out of phase.
21: Quad Chorus
is the standard type, and processes
the left and right channels independently.
22: XOver Chorus mixes the chorused signal of each
channel with the output of the other channel, produc-
ing a cross-over effect.
For either effect, the left and right channel signals are
sent through a two-band shelving equalizer before the
chorus effect is applied.
T Delay time 0…200 ms Set the basic delay length. Both
channels use the same delay
time.
S Modulation speed 0.03…30 Hz Set the speed of the LFO that
modulates the delay. For a stan-
dard chorus effect, use a low fre-
quency (approximately 1 Hz).
M Modulation depth 0…99 Set the depth at which the LFO
will modulate the delay time.
Higher settings will cause the
modulation effect to be more
pronounced. With a setting of 0
there will be no chorus effect.
LFO waveform SIN, TRI Select the waveform with which
the LFO will modulate the delay
time. You can select either sine
wave (SIN) or triangle wave
(TRI).
L Equalizer low –12 dB…+12
dB Set the amount of boost or cut
that the shelving type equalizer
will apply to the region below 1
kHz.

Dry:Effect balance DRY,
B1…B99, FX 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 chorus
sound will be heard. Other set-
tings set the proportion of the
direct sound and effect sound.

L Delay time L 0…250 ms Set the basic delay length for the
left channel.
R Delay time R 0…250 ms Set the basic delay length for the
right channel.

S
Modulation speed 1…99 Set the speed of the LFO that
modulates the delay. Higher
values will produce faster modu-
lation.

M Modulation depth 0…99 Set the depth at which the LFO
will modulate the delay time.
Higher settings will cause the
modulation effect to be more
pronounced. With a setting of 0
there will be no chorus effect.
LFO shape T+10…T–10,
S–10…S+10 Select the waveform with which
the LFO will modulate the delay
time. You can select either sine
wave (S) or triangle wave (T).
The numeric value selects the
character of the waveform. Incre-
asingly positive (+) values will
cause the peak of the waveform
to become broader, and increa-
singly negative (–) values will
cause the peak of the waveform
to become sharper.
