It is not done by crossfading, it is done by manipulating the CV's/currents that control the two filter stages. An ordinary VCF has the same CV to both stages, this has an additional control (Slope) that controls the first stage. And to complicate things even more the control inputs of the sections are interconnected in a way I don't really understand. I need to study it further to get it, will do when I have the time...and the will to take the panel apart!

I've always been curious as to what is going on inside to obtain the variable slope.
Is it for instance crossfading between several different outputs tapped at different poles?
