Thank you for the kind words! I don't remember exactly what I used on this but I think it is a Doepfer 101-2 low pass gate through a Pittsburgh Modular Crow filter. There also might be an oscilator in front of the LPG. It might be a Crow being pinged and run through another Crow. The reverb is a Meris Mercury 7, and it does sound great cranked, but I try not to do that all the time. As far as the voltages triggering and varying everything I don't remember but I usually start with a couple of waves through logic or a clock divider. I spend hours patching and tweaking to get it to sound human and realistic.
