OSC BAL

SUB OSC
Determines the volume level of the SubOscillator.

OSC VOL
This knob has two functions:
This knob has two functions:
1.
In the left half of its control range up to the center position (MIDI value 64), OSC VOL determines the
master volume of the three oscillators prior to the filter section input. The fourth voice-internal signal
source, the Noise Generator, is not affected by the master volume knob OSC VOL. The level of the
Noise Generator is controlled separately via NOISE VOLUME in the EDIT menu (see appropriate
section)

Noise Generator is controlled separately via NOISE VOLUME in the EDIT menu (see appropriate

2. In the right half of the control range from the center position to the far right, OSC VOL increases the
saturation intensity (Gain) for the input of the SATURATION stage (see appropriate section); however
this adjustment is compensated post-SATURATION stage so that when you adjust the gain you are
not actually increasing the volume, only manipulating the tonal spectrum in terms of saturation.

FILTERS
CUTOFF
Determines the cutoff frequency of Filter 1 and 2 (with exceptions; see CUTOFF 2).
Determines the cutoff frequency of Filter 1 and 2 (with exceptions; see CUTOFF 2).
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.

RESONANCE affects the first filter, the second filter or both filters.
ENV AMOUNT
Determines the modulation intensity of the cutoff frequency filter envelope. Depending on the FILT
SELECT setting, ENV AMOUNT affects the first filter, the second filter or both filters. In contrast to
virtually all other modulation intensity parameters in the Virus, ENV AMOUNT is a unipolar parameter.
The polarity of the modulation can be changed individually for each filter via the FILTER ENV POLARITY
function in the EDIT menu.

KEY FOLLOW
Determines the extent to which the filter frequency follows the pitch (Note Number) and the Pitch Bend.
Depending on the FILT SELECT setting, KEY FOLLOW affects the first filter, the second filter or both
filters. The function uses C 1 (MIDI Note Number 36) as a neutral starting point or base note: Regardless
of the KEY FOLLOW value, the filter frequency is not influenced at this pitch. When EXPERT MODE is
active, you have the option of freely defining the base note under KEYTRACK BASE in the EDIT menu.

FILTER BALANCE
Has different functions depending on the FILTER ROUTING setting (see appropriate section): In the
parallel FILTER ROUTING operating modes PAR 4 and SPLIT, it controls the balance of volume levels
between the two filters - or in actuality SATURATION and Filter 2.
Technically, in the serial FILTER ROUTING operating modes SER 4 and SER 6, the left half and the right
half of the control range address different parameters: When the knob is set to the far left position, you
will hear Filter 1/Saturation exclusively, whereas Filter 2 is blended into the mix as you rotate the knob
