I think another one could be really fun too! I'm a programmer currently going back to college to major in EE with a focus on DSP and writing some modules for the O_C seems like a fun project. The more the merrier!
I've been curious about maybe adding a pams to the mix now that the PNW's are super cheap on reverb. having 8 outputs of gates/triggers/envelopes/looping stuff seems like a great addition to the modulation part of my rack. I think with the quadrax and maaaaybe the zadar ( or even batumi? ) - i'd have most modulation duties under control and should start really focusing on messing with cv through logic and mixing.
Another thing now that I have this amount of space, a control surface / tactile playable element would be quite nice. I know tetrapad/tete and rene both get a lot of mentions.
