The LFOs
Now we can go on and solve the
mysteries of the signal flow as
determined by the FILTER ROUTING
operating mode SPLIT: Here Oscil-
lator 1 and the SubOscillator are
routed to Filter-1, whereas Oscilla-
tor 2 and the Noise Generator are
routed to Filter-2. Although the
sound sources are split into two
signal paths, you can still control
the volume levels of the different
elements as well as OSC VOL in the
usual manner.

THE LFOS
When you first started this series
of experiments with sounds, we
promised that many of the func-
tions the Virus can be “pro-
grammed” so that they are
executed automatically. You have
already learned how to control the
volume and cutoff frequencies of
both filters as well as the pitch and
intensity of the frequency modula-
tion of Oscillator 2 via “prepro-
grammed” envelopes. These
options are great, but you have
already encountered a number of
functions where it would be a
helpful if you could also program
them to be executed automati-
cally. And of course envelopes are
great modulation sources, but you
have to play a note every time you
want to initiate an envelope. Dur-
ing your experiments you probably
came across a function or two you
would like to be able to control
periodically - independently of
notes. Some features that come to
mind are traditional techniques
such as vibrato (periodic pitch con-
trol) and tremolo (periodic volume
