Fenix 1 filter section

I'd thought I'd upload a pic of the filters in the Fenix 1.  As discussed earlier, there are 3 and they are all different.

VCF1 and VCF2 are the simpliest. They both have a single audio input and two Cv inputs
CV2 in both is a variable input with a corresponding pot.  CV 1 is fixed to 1v/oct - to be used for filter tracking Both have 12dB/octave LP; 12dB/oct HP, and BP and there are three controls plus 3 outputs for each.

VCF 3 is more complicated. there are 3 audio inputs with their own pots (a mixer)
The LP filter has outputs for both 12dB/oct and 24dB/oct 
Again there are  two Cv inputs.CV 1 is fixed to 1v/oct. CV 2 is variable.
