Yep, good tips there! I need to focus more on using grouping better myself. I suspect I should be using more group multiband processing too.
Just FYI (and I mean this as a perhaps useful counterpoint to consider, nothing more) I think it’s erroneous to assume one “should” be doing something like multi-band processing just because it exists in the wide world of production tools.
We live in a super-abundant era of easy-to-access production tools, and I think a negative byproduct of that reality is that we think we need Everything and need To Do Everything. When, in fact, most of the great productions of the past / present / (hopefully) future were done with far, far less.
There are ‘pro’ producers, if you do a little googling, who think multi-band compression (as one example) is over-processing at its worst, and in most cases useless if not downright destructive in a production context (I can’t remember which article it was, but one had a producer calling it “Maul-the-Band” processing.
That said, the positive side of the golden age of digital music production is that we can try virtually everything out and decide for ourselves, so from that angle, sure, try it out and decide for yourself if it’s improving your productions. My advice is to just not assume you “should” be doing it.
Sorry for the potentially condescending rant / lecture mode, I’ll shut it down now. But I see a lot of this sort of “oh I should be doing mid-side on everything…” and “oh I should buy fabfilter multiband comp for my master bus…” and so on, and I just don’t think it’s the smartest route to better productions, etc etc.
