Hi Lugia, thank you for your answer! I'm aware of the four-tier rack (I own a two tier) but IMO that's not portable and/or secure for touring: it's simply huge, because of the form factor when having the 3 Moogs in a tier rack with an extra skiff on top. That's the main reason I'm looking for a case: to put them flat with a lid (with the added possibility to keep 'm patched in the case).

I think you might want to poke around this website for a while before dismissing the quad-tier idea: https://www.plattcases.com/ Platt almost certainly has a case available in their many lines that will make a quad-tier VERY portable. And, depending on the line you choose, pretty damn close to smashproof. Or, you could just go 100% bespoke here and put some rails, distros, and a suitable P/S in one of their off-the-shelf cases.
I gig out as well, sometimes. But this has less to do with that and much more with the idea that you can't 100% rely on music retailers for music solutions. Remember: they sell the majority of their gear to the usual MI crowd...which we pretty much AREN'T part of. And that determines what's available in their inventories. So, the sooner you get used to working outside of that set of constraints, the better, because your available options to solve technical issues go WAY up once you're able to do that effectively. Honestly, the amount of "sweat equity" one outputs in music these days NEEDS to include time/effort spent in researching potential options; with electronic music, good technical research goes hand in hand with the usual musical points of practice, performance, and study.
