AUDIO INPUTS AND AUDIO ROUTING
The Virus is equipped with two inputs for external signals. You can route these to its sound generat-
ing components and use them as carrier or modulator signals for the Vocoder.
OSC VOL / INPUT
When one of the two INPUT modes is activated, the OSC VOL knob rather than the oscillators con-
trols the level of the input signal patched into the Filter section and of course also the gain of the
SATURATION stage. In INPUT Dynamic mode, the level can increase surprisingly swiftly when you
play several voices polyphonically. The reason for this is that, in contrast to when you're dealing
with several oscillator signals, the voices are correlated because they are receiving 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 can also serve as level indicators for the left and right
external audio inputs. To this end, go to the CONFIG menu, select the menu item SYSTEM, and set
the Parameter LED mode to Input. When the parameter is set to Auto, the Virus automatically acti-
vates this level indicator mode when the selected SINGLE program accesses the external audio
inputs. The LEDs will flash rapidly to indicate that the inputs are being overloaded.
Der korrekte Pegel sollte an dem Gerät eingestellt werden, welches die analogen Signale liefert, da
so die AD-Wandler des Virus optimal ausgenutzt werden. Der Parameter INPUT Boost sollte nur in
Ausnahmefällen zur Pegelanhebung verwendet werden, da er erst nach den AD-Wandlern das Sig-
nal digital verstärkt, und somit die Aussteuerung der Wandler selbst nicht beeinflusst.
You should dial in a suitable input level on the device that is sending the analog signals. The reason
for this is that you want to feed the highest possible clean signal level to the analog-to-digital con-
verters of the Virus so that they will deliver the best possible performance. You should only turn up
INPUT BOOST as a last resort because it is located post A/D converters and boost signals digitally,
which of course doesn't affect the level of the converters.
Signals within the Virus may also be overloaded and may distort when their levels are too high.
Inherently, a virtual analog synthesizer's resonating filters and high level of polyphony lend signal
levels considerable dynamic potential. We could only rule out this type of distortion entirely by low-
