Good points Jim. It is one of the great selling points of the Yamaha boards, IMO. I use them all (not at the same time, of course) depending upon the style, song and my mood at the time. Some of the 2 -4 bar endings are very tasty...and by depressing the END button twice will give a sensible retard to most styles.

The Fill & Hit is a nice option if you want to your own custom ending.

I also like being able to use part of an intro as a fill between verses or at the bridge.

I got spoiled with the PSR 9000 which had dedicated buttons for each of the intros and endings. I believe the 2000, 2100 and Tyros all require selecting the desired intro/ending from the main menu if you want to deviate from the default....unless you have saved what you want into the User Style Memory. But, I can live with that, no problem.
