Hi Luigia! Only getting back to now. It was a busy week!!
Thank you very much the details.. i had to read your last post a couple of times but took away most of it, done some bedtime reading on the subject!

One last question. On the noted rack at the beginning of the post , i see 2x6 channels which by seeing his videos/routing seems to be fully used.
If i were to maximise space. Could i remove 1 mixer and use one along the intellijel quad? Since it does mixer too? You may say depending my needs I’d suppose.. but would this be a good way to efficiently manage hp?

I was thinking as alternative to use a doepfer 130-2 and see where it takes me.. but 2vcas now that understand better it purpose seems little and indeed 4 by default seems better!!

Thank you
