The Parameters

FM AMOUNT Controls the fre-
quency modulation intensity of 
the second oscillator by the first. 
Depending on the selected FM 
AMOUNT and the interval 
between the oscillators, the fre-
quency modulation generates 
everything from slightly to radi-
cally enriched spectra. In the Virus 
you have the option of combining 
the two functions called oscillator 
synchronization (SYNC) and fre-
quency modulation (FM AMOUNT) 
to generate new harmonic spectra. 
The characteristics of the fre-
quency modulation can be modi-
fied with the FM Mode parameter 
(in the OSCILLATOR EDIT menu). 
You may also select an external 
audio signal and have Oscillator 2 
modulate its frequency.

WAVE Selects among of 64 spec-
tral waveshapes. This parameter is 
identical to WAVE SEL/PW (see 
appropriate section) when SHAPE 
(see appropriate section) is set to 
the left half of its control range. 
However, in contrast to WAVE SEL/
PW, WAVE is always available 
regardless of the current SHAPE 
setting.

in semitone steps. Control range: 
+/-4 octaves.
