@Sound_trace, welcome to modular and Modular Grid!
A few comments:
-- re: modules, yes, Ladik and Doepfer have a lot of interesting modules you might look at. You have Genie from Non Linear Circuits in the rack above, have you looked at their other modules? They have a ton of interesting stuff IMO, I don't own any yet but I will be adding some of their Chaos and other modules in the next year. Metabolic Devices Coherence is interesting and also on my wish list -- I would call it an "esoteric comparator" basically. ADDAC has a lot of good and interesting modules, too many to name here. Erogenous Tones (which you already have in your rack) -- their Radar and Blip could give you a lot of additional fun, Radar is more than just 8 more envelope / lfos (as if that wasn't enough).
-- quickly eyeballing your setup, I'm not seeing a lot of logic or derivator modules. IMO that's a category you could beef up on especially given your experimental interests. Doepfer, Ladik, NLC have a lot in these regards. https://www.analogueresearch.com/product-page/artificial-neural-network when it is back in stock later this year is an interesting option.
-- I know you mentioned you sequence from the DAW. If you ever want to change that, Five12 Vector is something new for me I'm loving. A great sequencer with a big expander unit -- lots of firepower.
-- your query reminds me of a post I saw here: https://www.modulargrid.net/e/forum/posts/index/9928 That user is doing a lot of interesting stuff, you might check that post and suggestions
-- I'm very interested in eurorack control schemes, this TLDR post of mine interests me a lot and has gotten a whopping zero replies. BUT if you check out the 3 threads referenced near its top, you'll find a lot of interesting discussion, suggestions, and demo rack builds especially some generative rack builds by Lugia, see here: https://www.modulargrid.net/e/forum/posts/index/9906
-- beyond the question "what additional modules" I would suggest you consider "what proportions of what module types" as an interesting and helpful guide. I know JimH has many times said something like "sources < modifiers < control signals < utilities" -- that is not verbatim what Jim said, but kind of close. Some of your text above tells me you're probably already considering in a similar manner? Anyway, I think its a good suggestion from Jim and bear repeating; it has helped me to think of classes and #s of various modules first, then of "what specific next module do I need?" second. This helps build a coherent setup and have real synergies with the modules one already has.
The ideas above are not linear or exhaustive, just a bunch of responses that came to mind when I saw your setup and inquiry.
BTW the build you have above is already something I would be excited about. Good luck with your future explorations!
