ModularGrid Rack

Hey guys, so above is my rack that I have planned and the modules that I started with and actually own are Plaits, Marbles and Beads. My goal is to have a system focused around generative, granular, randomness and ambient.

I'm enjoying what I can do with the 3 modules but I'm looking for what might be a good module to add next, based on the options I have in the link above (or if you have any other recommendations I'm open to that as well!)

I'm leaning towards the quad VCA or qpas for more sound shaping options, but would love to hear what others think. Thanks in advance!
