I don't know if Pianoteq allows 4 microphones simultaneously, each with their own discreet outputs, and also allows them to be placed wherever they are needed. I suppose if that is possible, then yes, it could be useful with a multi-channel input on the AG. I just don't think Yamaha has any thoughts of that kind when they are developing their own top-of-the-range DP. They naturally want to cover every aspect of it themselves.

This is a common complaint with DPs though - the lack modularity. Most players prefer a certain sound (or changeable sounds), a certain action, a certain weight, and a certain set of features. To this point there has never been a satisfactory way to get the best of all aspects in one unit. It's frustrating.
