Given what you're looking for I suggest reading this excellent 4 part series on Pop/R&B/Funk/Jazz Brass from Sound on Sound (excerpt below from a fly-out box in Part 1 of the article). Well worth the $0.99 per part if you don't already subscribe.
Part 1: This new four-part series explains all you need to know about creating brass arrangements for a range of genres.
Part 2: The second in our four-part series deconstructs funk licks, discusses the implications of using live players and explains how to get more expression and feel into your sampled brass arrangements.
Part 3: A simple, catchy tune with a funky rhythm may be all you need to create a highly commercial horn hook — but harmony is also an essential ingredient in brass arrangements.
Part 4: We conclude our series with an overview of arrangement techniques and a peep into the world of big-band brass.

Although some contain playing styles that can work in a pop context, their deliveries generally lack the gutsy, uninhibited attitude required for pop, and their instrumentation and articulation menus are likely to contain significant omissions. Below are some of the better brass libraries and instruments that feature keyswitchable playing styles optimised for pop, soul, R&B, funk and jazz big band. They’ve all been well received by the sampling community, and with intelligent programming will add realism and colour to your horn charts. (SOS reviews in brackets).
