Thanks for detailed answer @JimHowell1970 and @Lugia
Indeed I need to change my way to procede. Looking for modules on Youtube isn't the best way to explore patches and trigger your creativity. You get easily seduce by sexy modules while being new. I totally agree

learning....

First yeah I have to take those moog modules out of the case to free the space in order to add a bunch of utility and logic modules (I haven't looked up for a matix mixer but now that I did, I cleary need one) I think I'll go for a joystick too (Planar² seems great fun)

yeah a matrix mixer and a handful of stackcables makes you modulation go a lot further - especially when paired with a kinks

For sound sources, it's clear that I need more. I was planning to get a piston Honda and some filters (one Polivoks filter for sure)

Not convinced - I count 6 in total (including clouds) already!

I was planing to get more VCAs (Hexvca Befaco) and a quad attenuator in order to throw a bunch of them in my patches to have more control of each patches and send them to my mixer Worn Soundstage. I believe this enough to have a good mix of all my patches, but I'm not 100% certain.

I would just go with 2 2hp trim modules for attneuation - and see if you need more vcas - you may not

I'm not planing to sell anything yet, I'll buy more modules and explore the patches. See what do fits the best and then sell what I don't need anymore.
Thanks a lot for bringing your expertise!

I haven't sold a single module in over 3 years

Mind you in the last 30 years I have only sold 3 guitars and a bass - to fund modules - I still have guitars and a bass though

"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
