Hi Bernie,
There is a fair bit to learn.
For auditioning styles for songs, I basically do my chord progression first. Then I go to the style picker, type in The song or sometimes the artist, and it comes up with with a list of suggested styles. (Some are definitely weird suggestions, ) but I just go thru the list till one stands out as being suitable.
Then I do the fills.
I basically just audition with the coyote wt synth and pick better sounds later using one of the vst’s. I could use sounds from Pa4x. Just not quite sure which way I want to go.
