5. User examples
The VC Waveform Processor A-116 is a very complex
module, which, especially through the modulation of
clipping level and symmetry parameters, can give any
number of sometimes drastic waveform transformati-
ons. It’s definitely worth systematically investigating all
its possibilities. There follow a few suggestions, which
may be helpful starting points.
D Begin with waveforms like sine and triangle waves,
which have few overtones. Experiment with diffe-
rent combinations of symmetry and clipping level,
and listen to the results.
D Fig. 4 shows an example of the different wa-
veforms which emerge from clipping a triangle
wave and putting it through different amounts of
symmetrical amplification.
D Try modulating one parameter with an LFO while
keeping the other constant. Experiment with diffe-
rent LFO waveforms and frequencies.
D Repeat this process with different settings for the
second parameter.
D Try the same with the first parameter fixed, and the
second modulated by an LFO.
D Modulate both the clipping level and symmetry at
the same time. Try different combinations of modu-
lation, such as
