I thought of getting a good 88 key controller and midi it to my Pa4x. I would have great styles and great sounds. It would also take less room.

I am not sure how I much control the controller would give me.(Important) I would use both keyboards in an “L” shape; one in front of me and one on either side.

1-Would I have to touch the Pa4x at all?
2-All opinions are welcome.
