NOTE:
LFO is an abbreviation of Low Frequency Oscillator. Whereas the Virus PowerCore's
main oscillators generate frequencies high enough to be in the audio spectrum, the LFOs
generate much slower oscillations, which are very useful for modulating any of the parameters
in the both the synthesis section and the effects section. There are 3 LFOs in the Virus Power-
Core.
The
mod matrix
itself
is used to route the outputs of 3 control ‘sources’ to six ‘destination’
parameters.
There are also 10 pre-defined parameters which can be controlled by
velocity
(how hard you
press the key on a touch-sensitive keyboard).
Added together, this means a total of 29 parameters can be controlled simultaneously by up
to 7 modulation sources, which allows for a great deal of movement, interest and expression
within a single sound.
So hopefully you now have a general overview of the way the Virus PowerCore works, it's
time to look in more detail at how to achieve all this sonic naughtiness…
Viewing Pages
To make things easier, the controls of the Virus
PowerCore have been organised into seven different pages. To view a particular page, click
on the corresponding name in the upper left of the Indigo pane.
> EASY
The Easy Page contains controls for the most commonly edited parameters, i.e. filter cutoff,
resonance, amp attack, FX Send etc.
> OSC
The Osc Page contains the controls for the oscillators section, including ring mod, FM and
noise. The controls for the mixer section are also located on this page.
> FILTERS/ENV
The Filters/Env Page contains the controls for the filter section and both of the envelope gen-
erators.
