CREATING MODULATIONS VIA
ASSIGN
As a rule, it is of course desirable to be able to
create modulation routing configurations on a
synthesizer. In other words, you want to enjoy
the freedom to combine different modulation
sources and destinations as you see fit. Some-
times you may come up with ideas for standard
modulations that the "hard-wired" factory mod-
ulation routing options simply can't satisfy. This
is why we opted to equip the Virus with a versa-
tile Modulation Matrix – you're sure to find it a
welcome addition. On the Virus, you can create
modulation routing configurations freely as you
see fit using ASSIGN options. They are located
in the EDIT menu, where they appear under the
name of – you guessed it – ASSIGN).
The three ASSIGN options let you control up to
six modulation destinations via up to three
modulation sources. Simply go to ASSIGN, se-
lect one of the modulation sources (SOURCE)
and one or several modulation destinations
(DESTINATION). Each of these configurations
features a parameter that determines modula-
tion intensity (AMOUNT). ASSIGN 1 can control
one modulation destination, ASSIGN 2 can
control two and ASSIGN 3 can control three
modulation destinations, each with independ-
ent AMOUNTs.
These ASSIGN options serve several purposes:
for one, they let you assign an external MIDI
controller, for example, the keyboard's modula-
tion wheel, to the desired parameter. You can
also chose to use the sound generator's internal
modulators, such as LFOs and envelopes, as
modulation sources. The control range of the
source may be limited via the AMOUNT values
or inverted so that the modulation occurs strict-
ly within the desired value range for the target
parameter. For your target parameters, you can
chose from among virtually all sound parame-
ters that feature an infinitely variable control
range – ergo, you have more than 100 modula-
tion destinations at your disposal! Since the
sources and destinations may be selected inde-
pendently, you may even modulate a single pa-
rameter by using up to three modulation
sources simultaneously. For this purpose, the
control signals of the modulation sources are
added up or overlapped. Conversely, you can
also modulate up to six parameters with just
one controller, which gives you all kinds of so-
phisticated sound morphing options. For this
purpose, select the same source for all three
ASSIGN options so that it modulates all six
possible destinations. This lets you radically re-
shape sounds and even transform or morph
them into entirely different sounds.

SOFT KNOBS
The Virus is equipped with two knobs that, rath-
er than being dedicated to predefined tasks,
may be assigned to different parameters by
you, the user. This option is quite handy, for it
lets you control directly the many menu param-
eters that do not feature a dedicated knob.
