Two month ago I asked about some recommendations to extend my Shared System with more stereo capabilities.
I now have a half full skiff and I think I’m finished with this project and I want to share a bit about my experience.
My current rack is here:
I now have a QPAS and I also replaced Echophon with Mimeophon. I liked Echophon, but never really found a use of the pitch shifting in my jams. (Except that I had a lot of fun with my 2yo kid playing with nothing more then a mic and the Echophon, but that was not very musical jam 
) Both modules are great and helped me to get my modular in the direction I wanted.
For modulation I went with a combination of WMD/SSF Modbox and Befaco A*B+C, instead of a second Math. They are still simple modules compared to Zadar or Stages. Modbox gives me 2 synced LFOs, a noise source and another sample & hold. No envelope generator compared to Math, but I already have three in my system. A*B+C is similar to ModDemix as it is a ring modulator/VCA/mixer, but it also provides two attenuverter and offsets. This is handy for modulating the SOS and Mix CV inputs of Morphagene, Erb-Verb or Mimeophon.
I put a 2HP Verb as an end of chain reverb. It doesn’t have much control (size, damp and mix), but it does sound nice for my use case. I don’t think it is a true stereo reverb, but it has stereo inputs and I only use it with a 10-20% wet mix. My original idea of using Worng LRMSMSLR would have allowed me to use the Erbe-Verb as an end of chain reverb, but having the Erbe-Verb as an effect for a single voice to go crazy without ruining the whole mix is a much better option.
I use a simple Intellijel 2x3 unity mixer to mix three stereo sources before going into the 2HP Verb. I also have a Befaco STMix for additional mixing. The STMix was the first module I received and I immediately enjoyed that I could use the stereo out of Morphagene without having the Morphagene as an end of chain effect.
I dropped my plan of getting an X-PAN. I had one on order, but they moved the shipping date from August to February 2021(!). I’ve confirmed this with another dealer: Make Noise won’t be shipping new X-PAN modules this year (at least not shipping to the two dealers here in Germany I talked).
Instead of upgrading to a Verbos Scan & Pan, I went with a minimal solution: A Doepfer 134-2 Dual Voltage Controlled Crossfader. The normalization of the module allows for panning with CV. It doesn’t have any knobs, but even the X-PAN would have no attenuator on the inputs. I’ve put it next to A*B+C and use one channel of it to control panning or crossfading and to attenuate the modulation.
Finally, to get back on topic (philosophy):
I’m glad I did not bought the Soundstage as it would have moved my patching to a more central mixing, as opposed to a distributed mixing. I now have Math, ModDemix, Optomix, A*B+C, STMix and a unity mixer for mixing purposes in ~250hp and this makes patching really flexible. For example, multing one mixer output to another mixer input is like having a huge matrix mixer. The last days with my current setup helped me to appreciate this approach.
As I’ve said, my stereo project is now finished. I bought most modules used, so I can replace them in the future without any financial regrets. But so far, I’m really happy. I hope this was somewhat informative. And thank you all for your input, not only for the replies to me, but for all discussions here in this thread.
