Yes, I'm aware of the limitations with repeated phrases but those phrases are much more detailed and realistic than most of the Biab midi styles. Maybe thats due to higher resolution? Playing an arranger vs Biab are two different things but the new ones sound really good. When was the last time you wrote styles for them, have you played the new ones? The best phrases are very good pro level arrangements. Don't get me wrong we can do a lot with Biab but when I sit at my Korg I can hear the style details and tbey are very good.

Both Korg and Yamaha have vast sound libraries to draw from and tailor each midi instrument part to work with those sounds. They use custom controllers to create articulations to example. A new Biab would need to go beyond basic GM into the world of custom midi. It would include it's own soundset and maybe include midi schemes to directly work with the big softsynths like Kontakt or Sampletank. Not simple patch selection, we have that now I mean all the custom midi control.

Just a few random thoughts.
