Howdy! One question: How much of this do you own already vs how much of it is your plan going forward? I'll give the obligatory "Behringer has questionable business practices" post, and you can do with it what you will. I personally own their 2600 clone and I love it, but a lot of their more recent copies of Mutable, Make Noise, and Xaoc modules are pretty ethically dubious. It's really hard to resist how cheap those modules are though, so I get the appeal!
On first glance, it looks like you have four complete voices included, and for a case this size I'd say that might be more than you want initially. I'd stick to two voices and really get to know your sequencing workflow. For Berlin style sequencing, I'd also recommend getting some sort of designated trigger sequencer. You can certainly do some interesting things with the clock out of the sequencers and the divider/multiplier, but something with direct control might be worth adding. Also some way to combine triggers can do a lot to mix up your pre-determined sequences, either by changing the timing and speed of advancing the sequencer, or divorcing the pitch sequence from the trigger sequence with the quantizer (Red Means Recording did a really good video on this technique a while back). A random source of some kind can do a lot to liven up a patch, as well a designated mixing utility for CV. I'm partial to matrix mixers or something like the TipTop MISO to get interesting combinations of your sequencers/LFOs/other CV before going into the quantizers. Cheers!
