Sure - but why because you can control these parameters by Sysex. I
control my DW8000 using two Phil Rees C16 Midi Slider boxes:
http://www.philrees.co.uk/products/sliders.htmAlthough if you do want true analogue fiddling - pots and resistors to
the cut off and resonance pins of all 8 filters is the way to go.
Then you can twiddly really quickly with no audible stepping.
However, the sysex way means you can record your twiddling in the
sequencer ;)
BTW: I Modded my Poly 800 here:
