I knew you would like the Roland. I liked it a lot but not as much as the Korg. Of course it is about 1/3 the price so that is to be expected. As you know I decided to return it, but it has some really great styles, sounds and features!
All the old styles I tried in it worked fine. A little tweaking necessary on some, but it's easy to do. FestiRock may be my favorite style on any keyboard, usable for a wide range of songs! You probably have it somewhere.
