Jim's spot-on, yet again...without the "boring" modules, the expensive stuff you have here can't operate to its fullest potential.
Synthesizers aren't just made up of things that make noises...you MUST have all of those utility and other sleepy-looking modules there, because without them, you have no way to directly influence modulation behavior over the other modules. If I were you, I wouldn't order or install ANY other modules at this point...instead, remove what you've NOT got on hand already, then try and rework the build to allow those. Otherwise, all you're building here is an expensive noisemaker...it won't have any of the nuance and controllability of a properly-implemented build.
