Sorry, I meant: 0.0 is completely unfiltered (dry) and 1.0 is
completely filtered (wet). I should go to sleep early today

Wouldn't the obvious thing to try first be a state variable filter?
Taking the Lo-pass, Band-pass and Hi-Pass outputs.
Then the parameter would in the first half of it's
range crossfade from LP to BP, and in the second
half from BP to HP.
I can confirm that mixing the outputs from an SVF so
I think in his "serial" LP-HP topology you're meant to use your parameter to
control the cut-off frequencies, not the gains. It makes possible to have
the filter be either LP, BP or HP at ANY time. If you use parallel LP-BP-HP
and tune the gains, it's very likely that at some point the filter's
