Hi,
I just change my KN6000 for the new PSR-2100. I freak on the operating system. We could do anithing we want in the same time while playing a style.
On the KN6000.... I was not able to look at the floppy to see the list of the style. When we press Load button all sound stpped on the KN6000.
The PSR let me select a midi while i'm playing a style !!
I could go anywhere in fuction system and all sound and style keep playing !!!

I really love my PSR-2100 !!!!
