Hi. I'm also fairly new to modular, about 2 years or so. I think it depends on what you're trying to do. This seems like a cool rack for sound design and ambient. If you're trying to do more rhythmic stuff I might recommend some more utility modules. Maybe try a disting and see which utilities you find the most useful. Multiples are great. VCAs that aren't Low Pass Gates seem like they'd also be a welcome addition. Random might be a nice touch. Inexperienced as I am, I'd say you're at the point where you should look less to sound sources or even effects, and more towards modulation, utility, and getting the most out of what you already have. It's incredible how much the smallest pieces can change everything.
