>2) Craig Anderton's 'Multiple Identity Filter' - this uses the four stages in a CEM3320 chip (as in some Doepfer filters), but with a clever switching arrangement, to allow the four stages to be in many combinations, some parallel, some in series etc, giving quite a few lowpass/highpass/bandpass/notch possibilities. I'm wondering what would happen if you made the switching electronically controllable...

Craig Anderton Who´s that Does he run a company or is it a DIY-filter
