Sorry to say that, but the MPC One solves a lot of problems. I can use it with any external gear, its capabe to send CV to the subharmonicon or midi to other synth, drum maschines etc. I was on this live quest also, but it solves that everything has to be connected at the same time. I sample the interesting parts or make a key group of a sound i like. At the end it has only two imputs and i only have two hands, so the amount of control i can do is limited. But i can play over the recorded snips. Every session adds to the sample pool. That is what is so great about it. It is work though, dont get me wrong, it feels like doing a job for free.
I tried to play with partners that helps more than more boxes, it means more compromise but if you gel its worth it. It also removes that work feeling a bit when your meetings are a little party too. (staying sober is good.)
Maybe the force is the better recommendation becaus it alredy streams from disk. (edit) (For me its a bit too large.) but i wait for the streaming update quiete for a while.
