VCF and VCO problems

[Niklas Rönnberg]

Hello!
I have some problems with a vcf...
http://www.itn.liu.se/~nikro/littleman/vcf.gif
The Hi/Lo switch works fine, but the cutoff does not effect the sound
that much. Yes, I can hear a difference but not enough. It's the same
with the res-pot, it don't do its work! Maybe I should use different
values of the cutoff and init-freq. pots, maybe it would be better to
use another sort of diodes? Any comments? Please

The whole project is here:

I has also some problems with the VCO. I think the FET is the problem

Is this correct?

Does anyone know the correct "pin-layout" for the BF256C? I think I have
reversed mine

The dist works fine, soft and crispy. :-)
Thanks for your help!
Regards 
/Niklas
