Hey, thanks a lot for your suggestions Lugia.
I've been doing some research on these modules as I didn't know them all. I think getting a pair Plaits is a great idea, and the chronoblob2 is also a fantastic suggestion.
Having the delay and reverb in two separete modules makes complete sense, however, I'm not totally sold on the Purrvrrb because it doesn't have any cv and I'd have to tweak it manually. Maybe I don't need the cv as much as I think I do, but I guess I'll make some more research for the reverb module.
The filters you suggested are pretty cool too. I like the G-Storm's one a lot, but wouldn't an Intellijel Polaris make more sense? It would save 2 hp and provide more filter types. Not sure if the Tonus just sounds better or if the mixer makes it worth the extra 2 hp.
I find the Optomix quite interesintg, isn't it like an VCA + VCF? if so, would I still need the Quad VCA at this point? having a couple of Plaits and being able to use the Optomix as an VCA may be enough, or how would I use the Quad VCA in this system?
I'm also considering replacing the Quadra with a XAOC Devices Zadar, there's not a lot of difference on the price and the Zadar seems able to provide many more shapes.
Complete noob as you see, but really appreciate the help and all the knowledge I'm getting here!
