Hi Sorid,
I just read your previous post. Three comments:
Did you ever consider the Expert Sleepers FH2 as your CV to DAW interface? It can output CV, gate, and clock. All outputs are available to be CV, gate, or clock (as well as LFOs and ADSRs). It's also expandable. I have one in my rack and like it. Though once you have your DAW booted, you have to quit your DAW to reconfigure it via the web interface. The onboard interface is a bit of a menu dive. However for the price and HP space, it's hard to beat. I also have a Temps Utile module. It can take a clock input and provide up to six clock outputs from /64 to x64. I believe Pamela's New Workout can provide the same if you're not comfortable with custom built stuff.
Zadar vs. Batumi. I think some features overlap but the Batumi is a quad LFO generator while the Zadar is more of an envelope generator. I own the Batumi with the Poti. I like it, but it's not as great as I thought it would be. I would consider having a traditional LFO as well if you're looking for real-time tweaking of values. It can be a little tricky when changing frequencies (faster/slower). The Zadar is in my wishlist due to the unique envelopes it can generate... but I also have the Intellijel dual ADSR. Having a traditional ADSR or two is also a good idea.
Also, buy a bigger case than you think you'll need. By all means add modules to your case like every HP is sacred. But when it comes time to expand, you'll get more value if you have rack space to spare. Of course, this means more upfront costs. But in my opinion it's worth it.
At some point you'll end up biting the bullet and hoping for the best. You might also want to develop a relationship with a reliable Eurorack dealer and ask for some help/suggestions as well. The good ones treat you like a client rather than a one-n-done customer.
