Pam's is the one module in your proposed setup that I have direct experience with, and I highly recommend it. When I said it was maxed out, I meant "EVEN Pam's is pushed to the limit here". I think it should be in your first purchase, more so than the filter (I have two, but for me they don't loom as large in modular as they do with Elektron boxes). It will help you to figure out what more boring modules you will want to complement the exciting ones.

That's good to know! I wanted to include it over the filter but thought it might not make sense with so little modules, but you've just convinced me to grab one alongside the Plaits! I think I will get those 2 modules first and go from there. Thanks so much for your help too, it's been great so much appreciated. They do have the Salmple in stock at my local dealer, so I'm very tempted by this too haha.
