SVF dual antilog pots

These seem to be hard to find and expensive.  It might be best to just
make the circuit itself more complicated, adding voltage control.

I have dual log pots, 50K which should be fine to do some experiments.

EDIT: tried the basic SVF and it oscillates for higher frequencies.
Possible problems: impedance of input resistor gets too low (50k pot).
