@Lugia, thanks, I'll read the whole thing! Curiously well timed reference to that book -- lately I've been trying starting compositions by getting strongly complementary ensemble sounds first, and notes later vs. the other order. Makes a big difference.
@Broken-Form and others, regarding your potential in-modular EQ needs:
-- suggest you check out Ladik EQs/Filters (https://ladik.ladik.eu/?page_id=7) these are small and cheap enough you could potentially handle several channels of EQ/filtering needs without a crushing HP or $ cost
-- also what comes to mind is Intellijel Mutamix for its ability to set levels and select among 3 bus outs. THAT would let you do some leveling and grouping before EQ/filtering. In the DAW I usually try to do as much group (vs channel) processing as possible as that often leads to a faster and better result. The group (stem) mixing approach in modular might have similar benefits. Not sure Mutamix is a great fit for you as you already have D.O.MIXX, but I wanted to at least mention the grouping/busing idea.
