Clavinova iAFC and Pianoteq

Supposedly it is DSP which uses microphones to adjust the speaker output for room compensation, produce spatial effects and mimic resonances such as when a singer standing near an open lid of a grand causes resonances within the piano.

I suppose the answer to the question would be "depends whether the piano can be used as a midi controller to PQ, and the laptop output fed back through the line-in of the Clavinova and whether the line-in is affected by iAFC, which seems unlikely."  I can't imagine Yamaha would bother including the feature of "Play your IPod as if it was connected to a Grand Piano."  Or maybe they would!
