Mosiqaar, you are free to use this or any style in a composition, which you can then copywrite. What you will be copywriting will be the melody and lyrics,if any,which is to say, THE UNIQUE CONTENT THAT YOU CREATED. The backing parts played by the styles are not intrinsic to your composition, they are just "decoration", and are free to be used in other compositions without infringing on your copywrite.This is assuming that you have indeed created some unique content! If you new-age "composition" consists of selecting a style and pressing the "play" button---------? I'm joking here, If you have a hit record using your X1 you need not fear any lawsuit from Ketron. They would probably be very pleased and feature you in their ads! Good luck.
