An acoustic grand piano is very, very rarely mic'd with one microphone...usually it is at least two...that's why the pianos in our keyboards are stereo.

With our keyboards, it is mainly done to enhance the player's experience, although having stereo for making effects more effective (pun intended) is sure nice to have in a PA system.
