Tips, tricks and other Words of Wisdom

The filter section of the Virus puts 
slopes of 12, 24 and 36 dB/oct. at 
your disposal. In addition, the FILT 
BALANCE knob lets you morph 
smoothly from slope to another, 
which effectively makes it infi-
nitely variable. Set the filter rout-
ing option to SER 6 and both filters 
to low-pass (LP). This gives you a 
serial setup comprised of a 24-dB 
and a 12-dB filter. When you set the 
FILT BALANCE knob to the center 
position, you end up with a filter 
that has a slope of 36 dB/oct. As 
you turn the knob to the left, 
you’re fading Filter-2 out and con-
sequently steadily reducing the 
slope until you arrive at 24 dB/oct. 
You can morph from 24 decibels to 
12 decibels by using the filter rout-
ing option SER 4. In this configura-
tion, both filters have a slope of 12 

dB/oct., so it doesn’t matter in 
which direction you dial the FILT 
BALANCE knob.

In Filter SPLIT mode, each of the 
two oscillators sends its signal into 
one of the two filters. Each filtered 
signal, in turn, is sent into a sepa-
rate VCA. The two VCAs can be 
spread in the panorama via the 
UNISON Pan Spread parameter. 
The difference to UNISON mode is 
that you only have one oscillator 
and one filter available for each 
side, although each with the full 
complement of voices.
