tomg vcf9a_sd

[Dr. Jörg Schmitz]

Hi all !

I have tried to built the serge vcf from tomg's cookbook.
( http://www.xavax.com/efm/synth/cbook/pics/vcf9a_sd.gif )

The problem is : I have found an offset at the lowpass output
which is dependent on the CV input (filter frequency control) :
low frequency : going down to -15 V
high frequency : going up to +15 V.
Resonance works, and there is a filter function at the different
outputs, but all with that offset changing, depending on the CV
input.

Any ideas ?

J.S.
