Take the DFAM and the Neutron out of the rack. The line-level outputs and MIDI are on the top of the unit. I think the same applies to the DFAM audio out (don't own one). By putting them in the rack you create new problems to solve at this point. Once you get going on modular, you'll want that rack space back.
As far as your modules... why? What will the Maths , Disting, and clock divider do for you and your set-up? What are the capabilities of the cv.ocd? Can IT generate clocks based on MIDI clock from your DAW or possibly a dummy MIDI clip running at the clock speed you desire? Can it support more than one clock? You'll probably want to clock the DFAM if you're using its internal sequencer alongside your DAW. You might need the Gate-Boost option for the cd.ocd.
You have the cv.ocd, the DFAM, and the Neutron at the moment. I would see how much you can get out of that set-up BEFORE you venture any further or bother with a rack or modules. I think you need some experience in using your new gear before augmenting it. You'll save yourself a lot of time and grief.
When you are ready to add more possibilities, I swear by the Temps Utile, Ornaments & Crime, as well as the Noise Engineering Mimitec Digitalis. With those three, you should be able to get some really nice modulation, and pattern generation. O&C and TU have a lot of possible functions like Eclidean patterns, quantizers, quad LFOs, etc. The Mimetic I find really useful since it has four 16-note CV sequencers in it and can be CV controlled to alter its patterns. Check out some Youtube videos on them and see if they are your cup-of-tea. I also have the Disting. But when I'm in the creative zone, having to break out the manual to figure out where the patch I want is and what parameters I can control tends to suck me out of my creative space and back into my daily technical life. The module is very powerful compared to its price... but it's so bloody hard to use.
That's my opinion and it's not necessarily the right one for you. But that's the advice I'd give you face-to-face if you were about to drop a lot of money on gear.
