Vortex Sound Research

I have very limited gear. 2x behringer crave and a neutron. This is the best I could do: take osc1(carrier), multiply it, invert one of the copies and patch both signals into the two inputs of a mixer. Osc 2 goes into the mixer CV. Mixer output to VCA. The carrier signal is mostly gone this way. Do you know other ways to achieve it? It think i dont have the four pole attenuator that could make it trivial. Also, is it possible to do something like wavefolding or other effects with only basic stuff? thanks
