This may not be useful for you, I know you mentioned getting more stereo modules. I’m writing this in case others are also looking to make their Shared System more stereo and I wanted to say that adding X-Pan alone is also an option.
I’m using that combination now, I was surprised how adding X-Pan affected my workflow and the end result.
I used to put Erbe-Verb as the end chain effect and I wasn’t certain whether I’d like the X-Pan on its own. In the end I enjoy it very much, I especially like to mix and pan multiple mono voices with the stereo reverb.
I’m doing mostly melodic ambient, here’s a random track recorded with this setup, patch notes in the video description.
