ACCESS VIRUS OS4

Filters

below. All other parameters as well 
as the settings for the oscillator 
modulations (LFO pulse width 
modulation and so forth) are dic-
tated by Oscillator 2. This doesn’t 
limit the functionality of the third 
oscillator by much (if at all), but it 
certainly facilitates intuitive han-
dling. The FM, Sync and Ring Mod-
ulator functions are not available 
for the third oscillator.

Like all other oscillators, the level 
of Oscillator 3 is controlled via OSC 
VOL.

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 fil-
ter 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.
