Hi there aoikimmery:
That makes 2 of us that have the PR54. It's a great piano that has similar features to the KN2400. It will play songs and load styles for the KN6000/6500 and the KN7000 but it does not go the other way.
No, you can not record into the PR54 through the Aux In. It does not record analog signals.
You can download the Owners Manual at
