The Virus also has a
sub-oscillator
,
which is used to add extra bass to a sound by tracking the
pitch of
oscillator 1
, only 1 octave lower.
In addition to the
3 oscillators
and
sub-oscillator
, there is also a
noise generator
. This gener-
ates ‘white’ noise, which sounds rather like the noise a television makes when you unplug the
aerial. This is useful for creating snare drum sounds, sound FX such as wind or surf, or simply
for adding warmth to the sound.
As if this wasn't enough, the Virus PowerCore is also capable of
ring modulation
(ring mod)
and
FM
(frequency modulation), both of which can be used to add extra harmonics and over-
tones, useful for creating more complex timbres like bells and electric pianos.
Mixer
This is where the outputs of
the oscillators, noise, and
ring modulator are balanced
before the resulting mixture is
sent to the filter section.
Filter
This is an extremely important stage of any subtractive syn-
thesizer, and the Virus PowerCore is no exception to this
with it’s
dual
fi
lters
, each of which can be assigned to one of
4 different types.
A filter is used to remove certain components (frequencies)
of a sound, whilst allowing others to pass freely. For
instance, a
l
owpass
fi
lter
will remove all the frequencies above a user-definable 'cutoff
'
fre-
quency, whilst all those be
low
will
pass
- geddit? The cutoff can be adjusted in realtime,
which results in a 'filter sweep' - the life-blood of many famous synth sounds.
