Hmmm...first up, lose the Moogs. Put them back in their cases and on their own power, as they take up way too much space given the functions you get. Plus, you can mount the Moog skiffs into their own multi-tier stand, like this: https://www.sweetwater.com/store/detail/Mother32Rk3--moog-3-tier-rack-kit-for-mother-32-dfam

Next, toss the multiple. This build is too small to support having functional space lost to mults, and you'll do better with stackcables or inline mult widgets. These really should be in larger systems, especially since you've got enough "real estate" for them. Also, buffered mults are mainly for regenerating CVs for distribution to CV destinations such as VCF cutoff, VCO frequency, etc, and there's not enough of that going on here.

The case is confusing...is this an Arturia cab, with a 6U on top and a 3U on the bottom, or...?

As for the pitch weirdness, try turning the coarse pitch control down to about halfway and then using the fine control to straighten out the tuning. Also, the Moogs have an interesting issue in that they're not 100% Eurorack-compatible, and they require one of these: https://www.modulargrid.net/e/erica-synths-pico-mscale to straighten out the issue. That 3 hp module shifts the CVs downward or upward so that they work with the +/- 5V scaling. Why does Moog do this? Well, Moog has a habit of being in their own "zone"...and in this case, it's the CVs that are the issue. Just be glad it's not the atrocity of the old Moog S-trig bus!

Sorry I forgot to precise both moigs are not in cases, I have both in the dedicate 'stand'

My case is an arturia rackbrute 3u, 88hp.
I save money for a the 6u, 2x 88hp.

I don't really use the moogs Vco, but yes I forgot, I do random with the subharmonicon's VCO.

Though I've learn, a tip woth th 1v/oct conversion of the Moog. (not of the Mother 32) send the KB output of the mother 32 toa buffered multiple.
