Lots of interesting modules here @toinouvltn. My personal suggestion would be to get a powered case, remove the RackBrute and the Quad Buffer, and add a Maths. It'll open up a lot of the other modules here, and its enveloping and LFOs will be a nice contrast to the Zadar and the Batumi (and I'll edit to add that that's not even mentioning all its other functions, attenuator and mixer especially coming to mind).
