It is important to remember if you are going from a Kn7 to a KN2600 with a style it will work. You will lose some quility, but it is acceptable. If you are going from a KN7 to another make keyboard, it is not the same. Whoever created the style for the Kn used the KN instruments. He worked on the style and made adjustments in many areas until he felt it was good. Given a set of instruments from another make keyboard the original creater of the style would begin to adjust and recreate. Hence big job and a possibility of not being acceptable.

If you have the time and you wish to put in the effort, it's a nice thing to do.
IMHO--I use the keyboard's styles, adjust them to fit your selected song, then play and add whatever your talent allows. I feel this adds to the player's ability to play the song and increase his musicianship. Over a period of time all the songs you play will sound better. Old kind of thinking--No, just trying to stay focused in this day of advanced technology. You know after using the automatic dialer on my phone I have forgotten all my important phone numbers. If I try to make a call from another phone, I'm at a loss. There is always something gained and something lost. Your choice.

I will use a style which I have purchased or downloaded if it has the little added effects that I need for a song. Example-God Bless the U.S.A.

For me, it's keep it simple, learn all about the keyboard and improve my playing. I learned to play full chords with the left hand because I knew it would improve my performance, I would sound better with another live sound. There are times when I sing with the style and my left hand feeding chords as a guitar or piano player would.
When I play the Lord's Prayer--no rhythm, style or cmposer--just strings with my left hand, an expression pedal and whatever I'm feeling (instrument) with mt right hand.

Wow, I really get into this stuff. I even forgot what the original question. I remember it was Scott, but what did he want anyway. ha ha ha ha
