So the XS plays arps. So does the G70.
That’s right. All a style is a collection of different arps.

It is just that the arps on the G70, T3 Pa 2x pro have more advance real-time features than the XS.

I guess people would start rewriting history and say arrangers from the 80s and early 90s did not have styles. After all, they had the same limitations yesterday as does the XS have today.
Remember the old Casios?
