CHAPTER 6
Synthesis Parameters

Determines the balance between the Oscillators
1 and 2 volume level.

Determines the volume level of the SubOscilla-
tor.

This knob has two functions:

• n the left half of its control range up to the
center position (MIDI value 64), OSC VOL deter-
mines the master volume of the three oscillators
prior to the filter section input. The Noise Gen-
erator and the Ringmodulator are not affected
by the master volume knob OSC VOL. Their lev-
el is controlled separately in the OSCILLATOR
EDIT menu (see appropriate section).

• In the right half of the control range from the
center position to the far right, OSC VOL in-
creases the saturation intensity (Gain) for the in-
put of the SATURATION stage (see appropriate
section); however this adjustment is compen-
sated post-SATURATION stage so that when
you adjust the gain you are not actually increas-
ing the volume, only manipulating the tonal
spectrum in terms of saturation. The intensity of
the remaining DSP effects available in the SAT-
URATION Stage is controlled via the OSC VOL
knob.

The volume of the noise generator. As with the
ring modulator, the volume is idependent off the
OSC VOL parameter.

The ring modulator multiplies the output of both
oscillator 1 and 2 to create interesting sounds
with rich enharmonic overtones. These over-
tones are highly dependent on the frequency
coherence of both oscillators and it’s wave-

changed, for instance use the OSC2 SEMI-
TONE parameter. If the RINGMODULATOR
VOLUME is zero, the ring modulator is switched
off. OSC VOL does NOT affect the ring modula-
tor level. Therefore the original oscillator signal
can be levelled independently of the ring modu-
lator. 

You’ll find another ring modulator in the effects
section of the VIRUS. It, however, processes
entirely different input signals.
