Doepfer

hello david,

from what dieter doepfer wrote, cv of the filter mode
is not possible with the ms20 filter design, or at least
it is very difficult to implement.
for me vc of filter mode is not an essential feature, but
i would really like to have vc of resonance. that would
be great, especially on a ms20 filter with it's killer
resonance behaviour.

best wishes

ingo
