Value Meaning
Low Pass ingle pole low pass lter for variable reduction of high frequencies. This effect is only included to 
ensure compatibility with older programs (early Virus models did not feature a dedicated EQ section).
High Pass ingle pole high pass lter for variable reduction of low frequencies. Also included for compatibility 
reasons.
The choice of “Distortion” effects are similar those available in the FILTERS menu, but here they treat the sig-
nal as a whole, i.e. not each individual voice. The difference is particularly noticeable when playing chords.
Intensity •
0 to 127: Generally determines the amount of effect. In the two lter models (see “Low Pass” and “High 
Pass” above), this is the cutoff frequency.
Modulation destination “Distortion Intensity“.
Analog Boost
Analog Boost can be used to emulate the frequency response of various real analogue synthesizers. Note 
that boosting bass frequencies will reduce the proportion of high frequencies in the resulting signal.
Intensity •
Off, 1 to 127: The degree of Analog Boost.
Modulation destination “Analog Boost Int“.
Frequency •
0 to 127: The frequency where Analog Boost is applied. Very high values will even boost mid-range frequen-
cies.
Chorus
Typically, Chorus is a thickening effect caused by modulating a pair of very short delay lines via a dedicated 
LFO, then mixing this with the original dry signal. In combination with Feedback, the Chorus effect in your 
Virus is also capable of anging, ensemble, vibrato or resonator effects. Note that if the Mix parameter is set 
to Off, the other parameters will not be visible in the menu.
