range of human hearing. This sig-
nal is not actually audible as a
vibrato effect. Instead, you’ll hear a
sound modulation, in some cases,
a very drastic one at that. Choose
the pure sine waveshape for Oscil-
lator 2. In conjunction with the
sine wave, the frequency modula-
tion generates very clear, in some
cases bell-like, spectra.

In the Virus you have the option of
combining the two functions
called oscillator synchronization
(SYNC) and frequency modulation
(FM AMOUNT, to generate new
harmonic spectra. Switch SYNC on
and experiment with the FM
AMOUNT. Also try out different
SEMITONE settings and the diverse
waveshapes of Oscillator.

The Virus is equipped with a third
master oscillator that lets you cre-
ate further oscillations and spec-
tra. You can access the parameters
of this oscillator, which are

THE MIXER SECTION
You have already come across two
parameters of the MIXER section:
OSC BAL
parameters of the MIXER section:
OSC BAL
determines the mix ratio
between Oscillators 1 and 2; in the
left half of its control range, OSC
VOL
left half of its control range, OSC
VOL
determines the master vol-
ume of the oscillator mix. In the
right half of the control range from
the center position to the far right,
OSC VOL
right half of the control range from
the center position to the far right,
OSC VOL

Now we’ll take a closer look at the
final control element, the SUB OSC
pot: It controls the volume of the
fourth oscillator, the so-called
SubOscillator, which always oper-
ates an octave below Oscillator 1.

The SubOscillator is mixed to the
Oscillator 1 and 2 master mix signal
as determined by the OSC BAL pot.
The master volume of the compos-
ite mix is controlled by the OSC VOL
pot. The only other parameter
available for the SubOscillator is
accessible via the OSCILLATOR EDIT
menu where you have the option
