Ahh - now I understand. I’m away from my rack at the moment, so have had to think through the patching in my head.
I could use my Disting EX as a pair of filters (or choruses), and the miniBrute’s filter as a 3rd. However, I suspect I need some better in-rack mixing to tie it together. Maybe a Doepfer a 138-s, or an Intellijel mixup perhaps? It would also be interesting to see what happens when panning the off-phase filters left and right.
