Well,
here's the prefab for the poly voices to 4 independent mono voices sorted from high2low (or low2high if you just swap the gui..) If I understood what you asked, this should do the trick:
4 voice split pitch high2low
I've also added a nice ambient synth around it so it can also give you some ideas of what to do with the 4 independent voices..
just let the prefab run for a while.. it gives all kinds of nice creepy spheres. I myself like the short bleep/plop rythm after 5 minutes or so :)
