The Parameters
Filter Section
(Encoder)
CUTOFF
Determines the cutoff frequency of Filter-1 and
2 (with exceptions; see CUTOFF 2).
CUTOFF 2 (OFFSET)
Controls the cutoff frequency of Filter-2. Nor-
mally, CUTOFF 2 does not operate absolutely,
but relatively to CUTOFF: The cutoff frequency
of the second filter is subordinate to the CUT-
OFF value you determined for the first filter.
However you can use the CUTOFF 2 knob to
dial in a re/- deviation in frequencies, i.e.
a higher or lower frequency (OFFSET). When
you set CUTOFF 2 to the center position, both
filters have the same CUTOFF frequency. In
FILTER EDIT Menu, you can access CUTOFF
LINK ON/OFF to sever the link between CUT-
OFF and CUTOFF 2. In this case the two knobs
CUTOFF and CUTOFF 2 are independent cutoff
controls for Filters 1 and 2, respectively.
RESONANCE
Controls the resonance (also called filter feed-
back or Q factor). Depending on the FILT SE-
LECT setting, RESONANCE affects the first
filter, the second filter or both filters.
ENV AMOUNT
Determines the modulation intensity of the cut-
off frequency filter envelope. Depending on the
FILT SELECT setting, ENV AMOUNT affects the
first filter, the second filter or both filters. In con-
trast to virtually all other modulation intensity
parameters in the Virus, ENV AMOUNT is a uni-
polar parameter. The polarity of the modulation
can be changed individually for each filter via
the ENV POLARITY function in the FILTER EDIT
menu.
