whereas Filter-1/Saturation is blended into the
mix as you rotate the knob towards the center
position.
Consequently, you must set FILTER BALANCE
to the center position if you want both filters in
series (in equal amounts) in the signal path.

ROUTING
This feature offers four filter routing options
which allow you to operate the filters in series
or in parallel:
- SER-4 The filters are switched in series; with
two poles each (12dB), both filters have the
same slope for a total of four filter poles
(24dB).
- SER-6 The filters are switched in series; Fil-
ter-1 has four poles (24dB), Filter-2 has two
poles (12dB) so the overall slope is equivalent
to six poles (36dB).
- PAR-4 The filters are switched in parallel and
feature two poles each (12dB).
- SPLIT The filters are switched in parallel and
feature two poles each (12dB). Additionally,
they receive independent input signal s (more
on this later). The stereo position of the sig-
nals can also be manipulated via the parame-
t e r T W I N M O D E PA N S P R E A D ( s e e
appropriate section) in the EDIT menu.

SELECT
This control feature is used to allocate the two
knobs
RESONANCE and ENV AMOUNT to the
first filter, second filter or both filters. The cur-
rently active assignments are indicated by the
integrated LEDs. To control both filters simulta-
neously via the knobs, you must first press both
buttons simultaneously. SELECT pertains to the
corresponding knob located on the Virus only,
but not to the sound parameters it controls.
These parameters exist separately in both fil-
ters regardless of the SELECT setting. This is
why for instance you should control the reso-
nances of the respective filters via different MIDI
Controllers. In actuality SELECT only deter-
mines if the knob in question sends its value to
the first filter, second filter or both filters.

KEYFOLLOW BASE
This feature determines the base note for the fil-
ter KEYFOLLOW: When you press the key se-
lected here, the filter frequency you determined
manually has priority - i.e. it is not influenced in
any manner - regardless of the KEY FOLLOW
setting (see appropriate section) for the filters.
As the interval between the KEYFOLLOW BASE
value and the keys increases as you move up
towards the higher end of the keyboard, the in-
fluence of KEY FOLLOW increases accordingly.
KEYFOLLOW BASE affects both filters simulta-
neously.
