below. All other parameters as well
as the settings for the oscillator
modulations (LFO pulse width
modulation and so forth) are dictated
by Oscillator 2. This doesn’t
limit the functionality 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.
Like all other oscillators, the level
of Oscillator 3 is controlled via OSC
VOL.

24-dB Filter Variations
You have two options for using the
24-dB filters of the Virus.
1. You can cascade the two 12-dB
filters in SER 4 mode.
2. You can use Filter-1 as a 24-dB filter
in SER 6 mode, whereby Filter-2
is faded out via FILT BALANCE (to
the left). If you want to create a
sound with resonance, you should
try out both options. When you do,
you’ll find that the sound of the
resonance is different despite the
fact that filters have the same
slope. The cascading option (SER 4)
gives you a higher Q factor with a
lower resonance peak. For direct A/
B comparison, you can store both
versions in consecutive SINGLE
memory slots and switch back and
forth between them at will.
