Thanks everyone for your thoughts! I didn't expect any comments on my first rack, but I'm glad to find such a vibrant community on ModularGrid.
I appreciate everyone's perspective here, and I can see there are many directions one can take when entering the world of modular synthesis. I'm happy to report that this rig is more than meeting my expectations and I've learned a ton so far interfacing with other gear that I already have, which was one of my main goals (the Data has been extremely useful for troubleshooting issues and for waveform visualization). Most importantly, I've already made some great sounds that I'm happy with, and am having a ton of fun. I really wanted to go full modular and build a "staging" rack so I could master each new module I purchase. While the B. 2600 looks pretty great for someone just starting to learn about synthesis, I felt like I already had enough gear with similar functionality and desired to be more intentional with every module I purchase as I focus and discover my sound.
