CHORUS

RATE

Determines the speed of the Chorus LFO.

DEPTH

Controls the intensity of the delay modulation
by the LFO.

The LFO modulates the left and right sides of
the Chorus signal antiphase, which generates a
true stereo effect.

FEEDBACK

Controls the amount of feedback in the Chorus.
On the chorus, FEEDBACK lets you boost spe-
cific frequencies in the delayed signal to create
a flanger effect. The FEEDBACK parameter is
bipolar; positive or negative feedback values let
you dial in different flanger characteristics.

MODE

In the Virus you have the option of using the ex-
ternal analog inputs instead of the internal os-
c i l l a t o r s a s s i g n a l s o u r c e s t h a t c a n b e
processed by the filters, envelopes and the in-
ternal effects.

The PART is not assigned an external

input but works with its own sound sources
(the oscillators and the Noise Generator) in
the manner of a conventional analog synthe-
sizer.
