I had been using this Ridgid case with custom cut foam for my MPC Live:

But I sold the Live because, well, Elektron. 
I still have the case and intend to eventually cut some new custom foam inserts for the Digitakt/Digitone combo. I might even be able to fit my Arturia Keystep if I’m clever.
However, I have to do a road trip with the DT/DN and haven’t had time to cut those inserts, so something just hit me today: why not try the foam packing ends that were in the original Elektron product boxes? Will they fit and will the case close?
YES!!!
Turned sideways, both the DT and DN fit PERFECTLY in the case with no movement to speak of when the lid is closed. There’s also about an inch remaining on one end that I put in a foam insert to keep everything stable, but the fit is snug enough that I don’t expect much movement.
I also super-glued the broken/wobbly bits of the Elektron foam inserts so they will last longer.
Would I put it in baggage claim? No, but I never do that anyway, even with good foam inserts. But until I get some custom inserts cut, this reuse of the Elektron packing materials will do.
EDIT: Aha! I flipped the Elektron inserts so the the “tall” side is down, and now my Arturia Keystep fits perfectly underneath the two Elektrons.
Will post a picture shortly.
