I ran across this Roland BK 7 Latin styles and I really like what I'm hearing. Does the bk 9 have these styles too?

I'm a Yamaha player but the Yamaha styles lack the kind of balls and authenticity that contemporary Latin dance music needs. I also LOVE the idea of a chord sequencer so I'm looking at the new Korgs and Roland.
