I have to agree with DNJ and the Pa4X76. I have one and started to convert my Yamaha and other keyboard styles, as I was familiar with them and thought it would be easier to populate my Korg. First of all, something is lost in the translation, as it were, and secondly, familiarity can be boring. I bit the bullet and delved into the sounds and styles of the Pa4X, bringing new life to my old songs. Like he said, you can bring over any specialty styles afterward.
