RELEASE
Determines the speed or rate at which the volume of the filter envelope decreases after the end of a
note. The higher the DECAY value, the longer it takes for the envelope to fall from its current level to
the minimum level, when the key is released.

SATURATION CURVE
The SATURATION stage in the filter section offers a selection of different saturation or distortion
characteristics. You can use these to add overtones to a sound. Beyond that, you are free to radi-
cally bend sounds using further DSP effects. The intensity of the distortion or DSP effects can be
varied considerably via the second half of the OSC VOL control range. For the distortion curves, this
intensity range is equivalent to a gain boost of 12 decibels, in the case of the "Digital" curve as
much as 24 decibels. A special feature of the Virus' SATURATION stage is that, despite the fact that
its gain is boosted, the signal level is kept constant via OSC VOL so that only the tonal color or tim-
bre of the sound is varied.
The SATURATION stage is always downstream of (post) Filter-1 irrespective of the given filter rout-
ing. Consequently, in serial filter modes, the SATURATION stage is always located between the two
filters. You can thus filter the oscillator signal conventionally with the first filter, distort the signal, and
process the distorted signal via the second filter as you see fit.
The Effects section of the Virus features a further distortion module called DISTORTION. Its design
is largely identical to that of the SATURATION, except for one major difference: whereas SATURA-
TION affects each voice separately, DISTORTION processes all voices collectively in the effects
section. This makes a huge difference in tone.
