Sub/Noise
The sub-oscillator beefs up the sound by adding a square or triangle wave
an octave below the pitch of osc 1.
The noise generator adds 'white' noise to the sound. It is un-pitched, and is
therefore used for percussion sounds, FX such as wind or surf, or for add-
ing a little warmth to pitched sounds.
> SUB SHAPE
This toggles the sub-oscillator waveform between square and triangle.
> NOISE COLOR
Changes the characteristics of the noise generator:
> Middle (0) :
Neutral ('white' noise, all the frequencies are evenly distributed).
> Negative (-64) :
Lowpass ('pink' noise, less top and more bass).
> Positive (+63) :
Hipass (bright and thin).
Velocity Mod
Several parameters in the Virus PowerCore can be
controlled by velocity. In practice this means that
these parameters can be set to respond to how
hard you press the keys. Think of a traditional piano
– as you hit the keys progressively harder, the notes
become not only louder, but also brighter (more overtones) and even very slightly sharper in
pitch. If you want to program sounds that respond in a really musical way to the nuances of
your keyboard technique, then it's definitely worthwhile spending some time on this section.
(There again, if your keyboard technique is comparable to that of a one-fingered chimpanzee,
perhaps you should move quickly on!)
Many of the following destinations are bipolar parameters, in which case, positive values
result in a positive offset as velocity increases, whereas negative values result in a negative
offset as velocity increases.
