If you want to play Jazz on a keyboard forget the style section, just stick with rhythm add a good set of bass pedals and a second keyboard (Yes folks it’s an organ) and play.
Alternatively get your self a quality drum machine and stick it by the side of the piano.
Finally go to a few Jazz clubs and listen to Real Jazz, as I can assure you that compared to Real Playing, all the Jazz styles on any arranger are TOTAL CRAP. (You will never make a Jazz musician using them as a guide)
If you do wish to use backing tracks or styles for your music in a live situation, create and play your own, do NOT use pre-canned versions. (The reason Keyboard Artists reach the top is because they play with minimal canned backing, (Normally just the Rhythm section) and spend time practicing and arranging, NOT letting the keyboard do the arranging)
If you just want to come back from the office/work and wind down, then stick on a suitable style and enjoy yourself. (Just don’t think that this makes you a professional musician)
