Good suggestions as always, thanks. I've definitely thought of moving the Moskwa and Ostankino next to the Erica sequencer. I change modules around every time I take things out of the case, so I don't mind moving stuff around. (And yes, I know, the organization here could definitely be improved.)
I've thought about adding Hrad, too, but alas... right now it seems to be out of stock everywhere in the world.
