ACCESS VIRUS RACK 101
Filter Section (Encoder)
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. Normally, CUTOFF
2 does not operate absolutely, but rela-
tively to CUTOFF: The cutoff frequency
of the second filter is subordinate to the
CUTOFF value you determined for the
first filter. However you can use the CUT-
OFF 2 knob to dial in a relative +/- devia-
tion in frequencies, i.e. a higher or lower
frequency (OFFSET). When you set CUT-
OFF 2 to the center position, both filters
have the same CUTOFF frequency. In FIL-
TER EDIT Menu, you can access CUTOFF
LINK ON/OFF to sever the link between
CUTOFF 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 feedback or Q factor).
Depending on the FILT SELECT setting,
RESONANCE affects the first filter, the
second filter or both filters.
ENV AMOUNT Determines the modula-
tion intensity of the cutoff frequency fil-
ter envelope. Depending on the FILT
SELECT setting, ENV AMOUNT affects the
first filter, the second filter or both fil-
ters. In contrast to virtually all other
modulation intensity parameters in the
Virus, ENV AMOUNT is a unipolar param-
eter. The polarity of the modulation can
be changed individually for each filter
via the ENV POLARITY function in the
FILTER EDIT menu.
