Dnj. Past years I have owned Korg,Roland & Yamaha. I have never had a problem learning new keyboard OS.
Yamaha forums contain the most 3rd party style downloads. Being a style player reading lead sheets these 3rd party styles give me many variations to play everyday...(with a whisky on the side...Ha!!!).

However To be able play with your ability I would only need a percussion & Bass track.

Best wishes for 2019 from the UK.
