66 CHAPTER 7The ParametersFilter Section(Encoder)CUTOFFDetermines the cutoff frequency of Filter-1 and2 (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 frequencyof the second filter is subordinate to the CUT-OFF value you determined for the first filter.However you can use the CUTOFF 2 knob todial in a relative +/- deviation in frequencies, i.e.a higher or lower frequency (OFFSET). Whenyou set CUTOFF 2 to the center position, bothfilters have the same CUTOFF frequency. InFILTER EDIT Menu, you can access CUTOFFLINK ON/OFF to sever the link between CUT-OFF and CUTOFF 2. In this case the two knobsCUTOFF and CUTOFF 2 are independent cutoffcontrols for Filters 1 and 2, respectively.RESONANCEControls the resonance (also called filter feed-back or Q factor). Depending on the FILT SE-LECT setting, RESONANCE affects the firstfilter, the second filter or both filters.ENV AMOUNTDetermines the modulation intensity of the cut-off frequency filter envelope. Depending on theFILT SELECT setting, ENV AMOUNT affects thefirst filter, the second filter or both filters. In con-trast to virtually all other modulation intensityparameters in the Virus, ENV AMOUNT is a uni-polar parameter. The polarity of the modulationcan be changed individually for each filter viathe ENV POLARITY function in the FILTER EDITmenu.
