CREATING MODULATIONS VIA ASSIGN

As a rule, it is of course desirable to be
able to create modulation routing con-
figurations 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 modulation routing
options simply can't satisfy. This is why
we opted to equip the Virus with a ver-
satile Modulation Matrix – you're sure to
find it a welcome addition. On the Virus,
you can create modulation routing con-
figurations 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, select one of the modulation
sources (SOURCE) and one or several
modulation destinations (DESTINA-
TION). Each of these configurations fea-
tures a parameter that determines
modulation intensity (AMOUNT). ASSIGN
1 can control one modulation destina-
tion, ASSIGN 2 can control two and
ASSIGN 3 can control three modulation
destinations, each with independent
AMOUNTs.
These ASSIGN options serve several pur-
poses: for one, they let you assign an
external MIDI controller, for example,
the keyboard's modulation wheel, to the
desired parameter. You can also chose to
use the sound generator's internal mod-
ulators, 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 strictly within the
desired value range for the target
parameter. For your target parameters,
you can chose from among virtually all
sound parameters that feature an infi-
nitely variable control range – ergo, you
have more than 100 modulation destina-
tions at your disposal! Since the sources
and destinations may be selected inde-
pendently, you may even modulate a sin-
gle parameter 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 sophisticated sound morphing
options. For this purpose, select the same
source for all three ASSIGN options so
that it modulates all six possible destina-
