Personally I’d choose Microcell over Beads. Microcell is the compact version of Supercell, which is a better version of Clouds. Better because it breaks out all the blend controls, has built-in stereo VCAs, and an aux CV, so you could modulate everything from a single source (like smooth random from Marbles or a looping 'shape' from Zadar). Also has a bunch of other modes you can access thanks to the SuperParasites firmware. Very versatile module.
