FOR OSCILLATOR-3
MODE The Virus offers a third mas-
ter oscillator per voice that you can 
activate whenever you need it. It 
lets you come up with even more 
complex sounds by adding more 
oscillations and spectra to the sig-
nal. When Oscillator 3 is switched 
on, (i.e. OSCILLATOR 3 mode is not 
set to the OFF position), the 
polyphony of the Virus decreases 
by up to six voices, depending on 
how many voices use the third 
oscillator in MULTI mode.

The second position of OSCILLA-
TOR
 3 mode is called SLAVE. Here 
Oscillator 3 is active, but – just like 
when it is set to the OFF position – 
no further parameters are avail-
able and visible. In this operating 
mode, Oscillator 3 is the ”twin” of 
Oscillator 2. It adds further oscilla-
tions, thus making the sound fat-
ter and more animated. Oscillator 
2 and 3 are handled collectively 
using Oscillator 2’s control features 
just as if the two were a single 
oscillator. All settings that you dial 
in for Oscillator 2 apply to Oscilla-
tor 3, with one exception – 
DETUNE. This parameter runs 
counter to that of Oscillator 2.
You can select the waveshapes 
individually for Oscillator 3 via the 
following OSCILLATOR 3 mode 
options: sawtooth, square (pulse 
width modulation), sine, triangle 
and all further spectral wave-
shapes. You have three further 
parameters available once you set 
Oscillator 3 to an individual wave-
shape. These are explained further 
below. All other parameters as well 
as the settings for the oscillator 
modulations (LFO pulse width 
modulation and so forth) are dic-
tated by Oscillator 2. This doesn’t 
limit the functionality of the third 
oscillator by much (if at all), but it 
certainly facilitates intuitive han-
dling. The FM, Sync and Ring Mod-
ulator functions are not available 
for the third oscillator.
Like all other oscillators, the level 
of Oscillator 3 is controlled via 
OSCVOL.
