Hi, it seems functional enough, but I don't see much in the way of "modular synthesis" for lack of a better word.
What's drawing you to Eurorack, or what do you expect to get out of this rack that you couldn't get out of a Digitakt plus an analogue monosynth for a third of the price (not counting the Oxi) or even a Polyend Play for half that.

Agreed with teataine, you have a fine synth here, but are missing out on two of the things that make modular synths so special - the ability to modulate parameters and the ability to create different signal paths on the same synth. I tend to think of my rack as a palette from which I build a new instrument each time I construct a patch. So, instead of getting modules that copy and paste what a monosynth or sequencer can do, think about things like modulators (e.g., lfos, random voltages, etc.), vcas, and utilities, and think about modules that allow for a lot of patching opprotunities. Feel free to check out my older comments, I've written a lot about utilities and planning a rack. I initially came here for advice myself with a rack plan that in retrospect would never have worked and would have left me dissatisfied with the hobby. Instead I restrained my buying to utilities and essentials until I had a solid foundation and understanding if what I was aiming for, only then branching into effects or drums or even oscillstors. Take some time to familiarize yourself with the above module types first, watch a ton of videos, and read manuals before buying. Hope that helps!
