dealing with this type of signal 
routing set-up, be sure to back off 
the input level a tad via the OSC 
VOL knob.

Alternatively, the RATE LEDs of LFO 
1 and 2 can also serve as level indi-
cators for the left and right exter-
nal audio inputs. To this end, go to 
the CTRL menu, select the menu 
item SYSTEM, and set the Parame-
ter LED mode to Input. When the 
parameter is set to Auto, the Virus 
automatically activates 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. 

Signals within the Virus may also 
be overloaded and may distort 
when their levels are too high. 
Inherently, a virtual analog synthe-
sizer’s resonating filters and high 
level of polyphony lend signal lev-
els considerable dynamic poten-
tial. We could only rule out this 
type of distortion entirely by low-

ering the fundamental output of 
the device significantly or by limit-
ing specific parameters. However, 
this type of problem occurs only in 
a very few, very specific scenarios. 
Since the problem is so context-
related, we chose not to lower the 
device’s output power or limit its 
parameters. Instead, we recom-
mend that you simply lower signal 
levels (Patch Volume, etc.) to pre-
vent undesirable distortion.

To help you keep an eye on signal 
levels, you can activate LED mode 
to visually monitor the levels and 
amount of distortion of the three 
audio outputs and two aux buses.
