encoder in the LFO section, you can have the
”ramp” rise or fall exponentially. If you choose a
triangle for your waveshape, the device will
generate an ascending phase (attack) and a de-
scending phase (decay). LFO Contour also lets
you determine the temporal relationship be-
tween attack and decay; in other words, their
respective rates.. Dial in the desired speed via
the RATE encoder.
You can also use S&H and S&G in ENV MODE
to come up with some attractive results: S&H
generates a single random value at the start of
a note (in this case, the RATE encoder has no
effect); S&G works in the same manner al-
though in this case the RATE value is crucial. It
determines the amount of time it takes to glide
from the previous to the new random value.
LFO 2
The design of the second LFO is essentially the
same as the first, so we’ll spare you the repeti-
tion of details SHAPE 1 and 2 are available as a
joint modulation target; the filter frequencies
and the Panorama position can be manipulated
individually. You may also freely select a param-
eter for your modulation destination.
SOFT KNOB 1/2
These are the two freely assignable controls.
The destination of these controls can be de-
fined within the Edit menu (SOFT KNOB 1/2
MODE). There are two parameters, one global
and one local i.e. applying only to the current
SINGLE program (which will override the global
definition if defined). SOFT KNOB 2 doubles as
a value control, and therefore only works as a
SOFT KNOB when the Virus is in Play mode i.e.
no Edit menu is selected. For each SOFT
KNOB, you can choose a short description from
a list in the menu, and this will be saved as part
of the SINGLE program. In Play mode, this will
appear in the display – to remind you of what
each SOFT KNOB does when you are playing
your Virus.
VOLUME AND PANORAMA
You probably noticed that the many of the
sound shaping options available in the Virus oc-
casionally influence the volume level. For in-
stance, an unfiltered sawtooth is naturally
louder than a highly filtered sawtooth because
whenever you blend a part of the frequency
spectrum out of the mix, you are automatically
reducing the overall volume of the signal. This is
why the Virus is equipped with a programmable
volume parameter for each SINGLE PRO-
GRAM. It enables you to balance out the vol-
ume levels of your sound programs.
Locate the parameter PATCH VOLUME in the
COMMON section of the EDIT menu.

Its value is set to 100 so that you have a reserve
or headroom of 27 volume increments when
you are dealing with highly filtered sounds.
