Thank you guys for all your comments.
Two observations :
1. No matter what anyone says or how they feel about this issue there is no way that you can access your registrations thru Songbook as fast as you could in the old way thru Performances.
2. I am not knocking the Songbook, it is a great feature. But to the best of my knowledge it was already there on the PA2X and PA800 more than ten years ago. So were the Performances. My beef with Korg is that they did away with the latter while there were actually quite a few musicians who had very good use for them.Not taking into account the Songbook it was also a lot more simple and pragmatic than the current Keyboard Sets.
