I placed the modules for easy patching (close proximity).
I reckon i will often use the disting as a sampler/drum machine so i placed pam next to it for easy wiring. Pam is also close to other osc for all kinds of modulation or clocking. Maths somewhere in the middle where it can provide modulation to anything. Four play as final mixdown also in the middle where it will often receive the audio from the oscs on the left and (typically) the envelopes from the black sequencer on the right. If the audio goes to the filters or in a submix than it will not come directly from the oscs, but hey modular will always have some spaghetti

Both maths and the behringer 121 can function as a mixer, so i have a little section for submixing stuff over there.
The filters are a bit the weak spot in the setup (they are the furthest away) and they are not necessarily the best around but i have a filter on the Grandmother and MS-20 to provide some extra color.
Although I m a bit cheating with the disting i have the following synthesis techniques covered:
* subtractive synthesis & classic oscs
* physical modelling
* west coast wave folding
* spectral synthesis
* additive synthesis
[disting cheating ahead]
* sampling
* granular
* wavetable
* polysynth
