The chord recognition problem was somewhat corrected with the newest software update.

My wife has a KN6000 which she loves. She feels the Solton X1 has the better instruments, and a lot of her love for the 6000 is it's lesser learning curve. For myself, I haven't found an instrument that stands up to the Solton's. I also prefer the Soltons styles and the dynamics of their styles. The 6000 has some really good styles and is a fine unit - obviously it will boil down to user preference between it, the X1 and PSR-9000. I do use a number of converted KN5000 styles on my Solton and find the styles very well done.

Find what you're happy with, be happy with what you find and enjoy it. )
