Zack, thanks for your suggestions! Will definetely take a look at VCV Rack.

The three 2hp modules with the stacked patch points (the walls) are the problem indeed. The flimsy knobs of the VCA don't help either. I'm thinking of moving the DPLPG right hand side to the Tiptop Module. But then you'll end up with a mess of cables on top of the the Z5000.

On the other hand these modules contribute so much. One thing I learned while compiling this tiny box is you have to compromise with functionality and ergonomics, and for me aesthetics too. Did I mention power consumption?
