Years ago when creating your own style was in I used drum rhythm books and bass books. Put the drum part into my Technics using Step-Time; One note at a time; and did the same for the bass parts. With my guitar background the rest was not too much of a problem.

This is what I learned:
The pros that were making the styles spent every day creating. I did not want to spend that time; nor did I have their talent.

So I learned to do what my friend Gary just posted. Find the styles that is close to the song you are working with, and then add your ideas. I use the pads as a quick fix, they do the job very well.
