Some great suggestions here
I'm taking a little leap here, but I use an iPad as a freely configurable midi generator (think Lemur) and the Shuttle Control - 16 freely configurable outs and a whole host of built in functionality - it really is an extraordinary combination! I guess it comes down to if you like playing the glass or not! I do
Also, the Octatrack, again with midi/cv conversion via the Shuttle Control or Yarns.
In the modular itself, I'm still working all this out and keep changing my mind, the ER-101/102 combo of course! But also Blinds for offsets, Batumi/Samara for phased LFO stuff and everything else this amazing combo can do! Stillson Hammer, Knobs, Maths, Kermit, Double Andore etc... I realise these are not controllers in the traditional sense, but they do allow for an awful lot of playability
