ModularGrid Rack

Much easier if you copy/paste the link into the comment, then we get to see your rack.

I'll let others speak to your specific goals as they're a bit out of my knowledge zones, but one thing to think of right off the bat is how you will be developing, changing, and manipulating your control voltages? You say you're sequencing and using the DAW for effects (how are you interfacing, exactly?), but one of the joys of modular is using voltages in unexpected and dynamic ways. I feel like this system as is gives a lot of audio manipulation but not much CV manipulation. For example, other than the two lfos (with only square or tirangle to choose from) on the Kobol, how will you be changing parameters over time without manual tweeking? Wiggling knobs is obviously fun, but a lot of what makes modular special is that the aspects of synthesis that are usually hidden inside a synthesizer are available to us out in the open, allowing for dynamic shifting of parameters over time. Look into utilities, which are the tools to make this happen. You have the disting, which provides a ton of algorithms, but is not the easiest to navigate and doesn't give you access to too many things at once. As for recommendations, unfortunately, there's no one size fits all, but attenuators, inverters, function generators, slew limiters, etc are great places to start looking. More lfos, or at least mults to help you make more of what you already have, should also be considered.

Anyways, there's no one size fits all as I said, and I don't want to recommend just buying more things, but I think you should consider where you plan to take this rack and seriously think about the utilities that will help you make the most of it. If you think of some motion you want the voltages to have, there's probably a utility to help with it.

One more note, if you're already planning on being heavily connected to the computer, consider a dc-coupled interface or something like the ES-8 or ES-9 (expensive, but very useful) to allow you to interact with VCV rack and other computer based cv manipulation tools. It will save a lot of hp and money in the long run, if that's a route that looks fun to you.

Best of luck.
