Yes that is definitely a viable solution, but the concept I am talking about would help those who don’t want to walk with a lap top, midi audio interface on a gig and trying to figure out how to get the controller keyboard, computer and software talking to each other seamlessly on a gig.
With the concept I am proposing, all you would have to carry on a gig is the hardware keyboard, a keyboard stand, a gig bag with your mic cables and pedals and your PA system.
