Thank you for all your input, guys! I decided to go for a Marbles clone.
Regarding the 0-coast and 0-ctrl, they are actually outside the case, like the SQ-1. I just added an extra row to include them, as they’re all integral to my workflow.
Regarding the many power sources, the rack is actually made up of five separate racks. One Rackbrute 6u, one Rackbrute 3u, one three tier Moog rack with the DFAM in its own case in the bottom tier. But the general layout is as you see it here on Modulargrid. The 3-tier Moog rack is the right side of the rack above (DFAM and above). Sorry for not making this clear.
I would love some creative feedback on workflow/ergonomics, Lugia. I’d be happy if you were to give it a go at restructuring it.
