The mystery device can't be rack mounted...
I think something else is afoot.
If you look at the width of the 'Recombinator', you see it is 782 pixels wide. Also it doesn't have the standard rack ears (or any at all). So that means it couldn't fit into Reasons rack at all (even if they made the rack wider).
So I reckon it's a VST i/o device that runs Rebirthlike alongside Reason using Rewire.
Do I get a prize?
