Did you really want to have two Pico DSPs?

Two obvious things you are still missing here : a mixer and a VCA. Ditch the second Pico DSP and you could get one of each from 2hp.

That said, I would start picking up the modules one by one and see what you actually need for the way you play. Some of these modules (Disting, Stages, BIA, Pam) have a lot possibilities and depending how you use them you might change your mind about the others, especially in combination with your other gear.

As I put 2 voices, I considered having a different effect for each of them.
It may be a reflex from using effect pedals on my synths and drum machines :)
I thought Optomix was a good option to start with, cause he has low pass gain, vca and mix functions. As reading your advice, I realise that not really. ;)
Starting my rack project, I was interested by Unify mixer, and intelligel quad VCA. Then I realised that I could use optomix to mangle the sounds and gain space. I'm curious about your opinion on this choice and the alternative options.
Here is where my rack is stuck for the moment, because of money ;) Don't hesitate to complete it, I would be glad.
46 HP left !!! :))
