...I also enjoy is that the same Intro & Ending is different depending if you Play it in a MAJOR key or MINOR key!.....
Nice!
But as you know, this is not any new feature at all, it is, and has been like this at many keyboards for a long time, not only at Rolands.
Some styles has huge difference between major and minor intros, others not as much.
Another fine thing is that the different intros sometimes can be great as bridges etc.
