The Steiner filter tracks really well on the PB. That means you can use the filter as a sine wave oscillator running into the ladder for a pretty massive sound. I've attached a basic template--just the tracking set up for the ladder to run as a sub with VCO 2 and its sub detuned slightly from VCO 1. From there you can dial in the cutoff to be a fifth or even track the ladder in the same way--although with the filters running through the ladder you'll get quite a different tone.
