WAVE SHAPING
The Wave knob controls the initial wave shape from the VCO. In the anti-clockwise position a sawtooth is
generated, in the clockwise position a pulse is generated, between the two positions the wave shape alters from
sawtooth through various sawtooth/squarewaves to a 5% pulse. The waveform is fully variable with no fixed point.
The Mod knob controls the amount of triangle modulation (from the VCLFO) or envelope modulation routed to the
waveshape. Pulse width modulation can be created using this method.
The Wave Mod socket and associated Amount pot is the way of externally controlling the waveshape generated
by the VCO. The Amount pot also acts as an invertor. So that the initial wave shape can be swept both positively
and negatively. For example the wave can be converted to a pulse wave using a positive control voltage and
having the amount knob turned clockwise (be aware of voltage level and amount knob position) like wise using a
positive control voltage but with the control knob turned in the negative position a pulse wave can be converted to
a sawtooth. This is a very important control and learning how to use it along with what to use it with will create
very unusual waveshapes.
This is the unmodified output of the VCO and has an output voltage of +10v ( in mode) as it concerts to the
5% pulse the output will have a +/- voltage of 10 volts when the sawtooth component of the wave shape has been
removed the square/pulse wave will be approx - 10v.
