AUDIO INPUTS
You can also opt to use external
audio signals in place of the onboard
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 other PART, be
routed freely to one or two of the
six audio outputs.
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 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.
As a rule, when you’re processing
external audio signals, you need to
distinguish between the following
two operating modes:
