We were discussing mixers for live performance in another thread and the solution I settled on was SSF Vortices + as many 2hp mixers as you need for sends. The other option I entertained was chaining a Doepfer A-138n into an A-135s. You don't get voltage control over pan though.

There are also a few Ladik modules that almost worked for me, but came in one channel short for my rig. With neither space nor budget constraints I would probably have gone for the Hexmix-Hexpander combo. Even without the Hexpander, having mutes and EQ on the channels is a draw for the Hexmix. (Shame the midband isn't sweepable!)
