AUDIO INPUTS
You can also opt to use external audio signals
in place of the on-board oscillators for the
sound programs or MULTI PARTs. The VIRUS is
equipped with two inputs for external signals.
You can route these to its sound generating
components (the filters, the saturation stage as
well as the volume and panorama stage) or
patch them directly to the effects section of the
VIRUS. External audio signals may also be used
as carrier or modulator signals for the vocoder.
Any PART that you use to process an external
audio signal in MULTI mode can, like every oth-
er PART, be routed freely to one or two of the
six audio outputs.
As a rule, when you’re processing external au-
dio signals, you need to distinguish between
the following two operating modes:
-  DYNAMIC  To make external signals audible
in this operating mode, the volume envelope
must be triggered via a note. This option, for
example, lets you create typical gater effects.
INPUT Dynamic mode is also polyphonic. If
you set the KEYFOLLOW value for the filters
to 100%, the resonant frequencies of the fil-
ters and oscillators can be played in a tem-
pered manner via the INPUT signal. This lets
you play entire chords as well as arpeggiator
lines using the filters. The noise generator is
also active in INPUT mode.
-  STATIC  In Input Static mode, the external
audio signals are audible via the output with-
out having to trigger a note. Bear in mind that
the oscillators as well as all functions that
have to do with trigger and pitch are disabled
(envelopes, LFO Env mode, keyfollow...) In
INPUT Static mode. When you set the device
to this mode, one voice of the VIRUS is acti-
vated automatically. If you select a stereo
source (L+R) for INPUT Select, two voices are
activated much like in UNISON mode: Twin.
In this case, you can also use the UNISON
Pan Spread parameter to determine the basic
width of the panorama and UNISON LFO
Phase to shift the LFO phase position be-
tween the voices.
-  TO EFFECTS  An alternative to INPUT Static
mode, here the audio signal is routed directly
to the effects section of the SINGLE program
or PART. This mode doesn’t use the voices of
the VIRUS, which means that its polyphonic
performance remains fully intact and availa-
ble. The filter section is unavailable in this
mode.

OSC VOLUME / INPUT
When one of the two INPUT modes is activated,
the OSC VOL knob rather than the oscillators
controls the level of the INPUT signal in front of
the Filter section and of course also the gain of
the SATURATION stage. In INPUT Dynamic
mode, the level increases quite rapidly when
you play several voices polyphonically. The rea-
son for this is that – in contrast to when you’re
dealing with several oscillator signals – the
voices are correlated because they are receiv-
ing an identical input signal. In the event that
the VIRUS generates distortion when you’re
dealing with this type of signal routing set-up,
be sure to back off the input level a tad via the
OSC VOL knob.
INPUT LEVEL INDICATOR
Alternatively, the RATE LEDs of LFO 1 and 2/3
can also serve as level indicators for the left and
right external audio inputs. The VIRUS automat-
