The Parameters
TIME Sets the bipolar time parameter
for the filter envelope. It
determines the envelope’s
response once it reaches the SUS-
TAIN phase (see appropriate section):
If the knob is set to the
center position (12 o’clock) indicated
by the mathematical infinity
symbol, then the SUSTAIN level
remains constant through to the
end of the note; if you turn it
counter-clockwise to the left
(towards FALL), then the level
drops off at an increasing rate
towards the minimum level; If you
turn the knob clockwise to the
right (towards RISE), the level rises
at an increasing rate to maximum.
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.
FILTER-EDIT-MENU
SATURATION CURVE The SATURA-
TION 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 radically 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 timbre of the
sound is varied.
The SATURATION stage is always
downstream of (post) Filter-1 irrespective
of the given filter routing.
Consequently, in serial filter
modes, the SATURATION stage is
always located between the two
filters. You can thus filter the oscil-
