So, basically the answer of the Stein67's question is, yes, we can use the styles but not the intros/endings because they are recogniseable.

Personally, I do modifications to the style itself to suit my songs better and don't use the factory intros and endings but write my own ones except for one bluegrass song where I need to come up with my own intro and fill.

Ian, thank you for enlightening on the subject. The answer was close to logic but it's always better to read it written by a Yamaha demonstrator.

Kind regards,
Geoge.
