I'm not good enoughj with the tech - but midi is just a control system that turns things on and off, doesn't matter what they are. Nothing to do with music except in the name. Wikipaedia talks about using it to control a sampler to play back recorded sounds.
No doubt this is not a cheap or easy option, but it is do-able (is that the proper use of the suffix 'able'? I cringe when people talk about 'breathable' shoes, or 'recordable' televisions!).
