Distortion

Curve  Here’s a rundown on the 
various DISTORTION modes:

 

OFF    The signal is not processed.

 

Different analog distortion curves 
with different characteristics and 
intensities. 

 

DIGITAL    Digital distortion with 

hard clipping. 

 

SHAPER    Sine characteristic 

curve with several wave cycles. 
With the Shaper, you can drasti-
cally warp signals. In some cases, 
the results are similar to the spec-
tra of linear frequency modula-
tions.

 

RECTIFIER    Continuous rectifica-

tion of the signal; this type of dis-
tortion is independent of the given 
level.

 

BITREDUCER    Continuous reduc-

tion of the digital signal’s bit 
depth; generates digital quantiza-

tion noise.

 

RATEREDUCER    Continuous 

reduction of the digital sampling 
rate; generates digital aliasing. 

 

LOWPASS     -pole low-pass filter 

for moderate processing of high 
frequencies. 

 

HIGHPASS    1-pole high-pass fil-

ter for moderate processing of low 
frequencies.

Intensity  For the distortion curves, 
this intensity range is equivalent 
to a gain boost of 12 decibels, in the 
case of the ”Digital” curve as much 
as 24 decibels. A special feature of 
the Virus’ SATURATION stage is 
that, despite the fact that its gain 
is boosted, the signal level is kept 
constant so that only the tonal 
color or timbre of the sound is var-
ied.
