hello zoran,

you can always use a mixer, a multiple and a vca and do
a patch to get voltage controlled resonance.
patch the unfiltered signal to one mixer input.
patch the mixer output to the filter input.
patch the filter output to a multiple.
take the signal from the multiple and patch it
into the vca. then patch the vca output to
another input of the mixer. opening the vca is
like increasing the resonance. when using a polarizer
instead of an vca you can overdrive the resonance
or you can invert it.

best wishes
