Thanks a ton for your answer, I can't stress enough how useful it is to me :)
On drum modules: alright, it makes sense to drop them all + I didn't mention that I also had a DFAM. I totally forgot about noise modules indeed. Do you have preferences on these? I found the entropy by Zlob, that also has an expander that adds blue and purple noise. The noise and filter from Verbos seems interesting too.
Maths: check ✅ To me, another argument for going with Maths is also the ton of ressources available. I will also wait a bit before buying the Joranalogue, as they feel a bit less necessary than a number of other modules. Also, I feel like the Just Friends already offers nice ways to screw with clocks.
On Borg, would you go for the Borg 2 rather than the dual borg? I'm having difficulties to find any of them but I'm planning to trade my Jove 80 as soon as one of them is available.
Yeah, I didn't really pay attention to the order of the modules, I'll make an updated version of the rack once I digest all the information you gave me.
Thanks a lot again for your help!
