Audio Inputs

You can also opt to use external 
audio signals in place of the on-
board oscillators for the sound pro-
grams or MULTI PARTs. The Virus is 
equipped with two inputs for 
external signals. You can route 
these to its sound generating com-
ponents (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 mod-
ulator 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.

As a rule, when you’re processing 
external audio 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 filters and oscil-
lators can be played in a tempered 
manner via the INPUT signal. This 
lets you play entire chords as well 
as arpeggiator lines using the fil-
ters. The noise generator is also 
active in INPUT mode.
