Tips and tricks
To come up with a fatter sound, you should also
dial in the second oscillator (set OSC BALANCE
to the center position) and use DETUNE to do
just that to its pitch (relative to the first oscilla-
tor).

Next to LFO1, LFO3 is also able to generate
pulse width modulation. However, unlike LFO1,
LFO3’s modulation algorithm was tweaked spe-
cifically to deliver what we consider hip pulse
width modulations. Note that LFO3 PWM often
delivers smoother results, particular a softer,
tighter sound for pads. Another advantage of
LFO3 is that it frees up LFO1 so that you can
use it for other sonic chores. By the way, KEY-
FOLLOW should also be activated for LFO3.

OSCILLATOR SYNC/FM
On the VIRUS, Oscillator 1 is always the com-
ponent that determines the frequency for the
two functions oscillator synchronization (SYNC)
and frequency modulation (FM). This means
that you can use both of these options at the
same time. With frequency modulation, you can
create extremely complex spectra, whereby in-
harmonic frequency components are filtered
out (so to speak) in the course of synchroniza-
tion. An infinite number of new harmonic spec-
tra can be thus generated with the parameters
FM AMOUNT and OSC2 SEMITONE. Moreover,

OSCILLATOR 3
The VIRUS offers a third master 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 signal. When Oscillator 3 is switched on,
(i.e. OSCILLATOR 3 mode is not set to the OFF
position), the polyphony of the VIRUS decreas-
es by up to six voices, depending on how many
voices use the third oscillator in MULTI mode.

The second position of OSCILLATOR 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 available and visible. In
this operating mode, Oscillator 3 is the "twin" of
Oscillator 2. It adds further oscillations, thus
making the sound fatter 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 Oscillator 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 spec-
tral waveshapes. You have three further param-
eters available once you set Oscillator 3 to an
individual waveshape. These are explained fur-
ther below. All other parameters as well as the
settings for the oscillator modulations (LFO
pulse width modulation and so forth) are dictat-
ed by Oscillator 2. This doesn’t limit the func-
tionality of the third oscillator by much (if at all),
but it certainly facilitates intuitive handling. The
FM, Sync and Ring Modulator functions are not
available for the third oscillator.
