Depends...if you put the Mescaline in a typical cab, that would tend to get messy in the way I describe above. But if you put it in a 1 x 126 cab, now...that would actually preserve the "ecology" of the Mescaline while, at the same time, housing it in something less precarious. And yep, it fills that from end to end. If you wanted to do a lot of gigging with the Mescaline, this might be a good solution. However, you would still have the potential of patchcord snarls right over the middle of this.
How I deal with this: the Softpop and bitRanger aren't in any fixed position, so if they need to go somewhere for the sake of patch clarity, that's not a problem. The Mescaline is also not necessarily "fixed", either...but it tends to stay in a position that allows it easy access to the "non-movable" Dupont pin devices, such as the AE and the FHC quad comparator. But they don't need to go "outside" their patching paradigms, since each device also has 3.5mm I/O of some sort, so there's no need to start stringing Dupont wires all over the whole modular "sandbox" station in here.
The other key to this is the sandbox itself. This has 80 1/4" patchpoints in of itself (Furman PB-40s, all non-normalled) which, along with my unkillable Mackie 1202 (1st gen), allow me to centralize the signal routing for this entire subset of gear. Plus, it lets me have a pair of FX processors (Zoom 9120, Korg SDD3300), a quad gate (Symetrix) and my MOTU interface for either audio or CV/gate/trig work right there, all ready to go. And yes, I did implement the inserts on strips 1-4 on the Mackie, where I use some little short patches to handle the duties of the "normalization" link.
