Since we are on this topic, here are some of my thoughts..
The best thing about today's arrangers is not the styles, but the versatility of the arranger..Arranger play, Media play, straight up play (no arranger), and the best to me, the ability to filter out parts of a style to be more realistic..
I absolutely hate the busy styles (yes Yamaha is king here)..and than to add pads to make it busier yet
If you need all that arranger backing..you better look at your playing ability to make a style useful...
I like the same band members on every tune..I want my drummer , bass player, guitar player, sax player, and I will take care of the keys.
This band is enough to cover any venue.
Stripped down styles can go a long way to making a performance sound realistic..and more enjoyable for the audience, especially arranger play all night long..
I can count on two fingers how many Yamaha styles I liked enough to use on my keyboards
..and now with the great BK styles, I pass right over those two Yamaha styles..
