Audio Inputs

AUDIO INPUTS
You can also opt to use external audio
signals in place of the on-board oscilla-
tors 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 compo-
nents (the filters, the saturation stage as
well as the volume and panorama stage)
or patch them directly to the effects sec-
tion 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 sig-
nal in MULTI mode can, like every other
PART, be routed freely to one or two of
the four audio outputs.
The Virus Rack is equipped with two
audio inputs on the back panel. Addi-
tionally the left input is accessible on the
front panel. When you plug a cord into
the front input, the rear left input is dis-
abled.
As a rule, when you're processing exter-
nal audio signals, you need to distin-
guish between the following two
operating modes:
DYNAMIC
audible in this operating mode, the vol-
ume 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 make external signals
to 100%, the resonant frequencies of the
filters and oscillators can be played in a
tempered 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 exter-
nal audio signals are audible via the out-
put without having to trigger a note.
Bear in mind that the oscillators as well
as all functions that have to do with trig-
ger 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 ste-
reo 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 pan-
orama and UNISON LFO Phase to shift
the LFO phase position between the
voices.
