fonitrOnic Wasp VCF clone
My own approach to that VCF.
I substituted the resistor values of
the filters core with more conventional
ones and added a simple exponential
current source: Nothing fancy since
this filter won't selfoscillate anyway.
Thus no 1V/oct calibration or temperature
compensation is needed.
I also used three remaining inverter stages
of the 4069 for implementing seb francis
cmos distortion circuit of his box-o-trix.
To make this module complete i added a blend
circuit to balance the wet/dry signals
or even external signals.
The 2nd CV in (FM) provides an attenuverter
(thank you Funky40 for this idea. it's
allways good to listen to a hardcore patchers
advice).
On the PCB the output of the filter will be normalled to the
distortion input and the 1st blend input.
The output of the distortion will be normalled
to the 2nd blend input.
