Only the order. If it were up to me, I'd put the M32 on the bottom because of its chiclet-type keyboard controller, then the DFAM above. Top row (great choices, btw) really should be (left to right) ES-8, Mother's Helper, uScale, Maths, Disting, A-178. That puts your control functions all in one area, CV stuff down the middle, and then the theremin controller all the way on the end to keep the aerial away from the synth so that you don't have to deal with random pickup issues while tweaking the other knobs. By putting it over the Moogs' patchpoints, you're pretty assured that working with the rest of the synth doesn't cause the A-178 to pick up on random hand motions near it.
