The adaptive styles are good, they *do* jump from Main variation A through D depending on how hard you play; it actually works pretty well.
The Unison styles; I actually don't like them, because they keep randomly inserting cymbal crashes when I play a bit too hard. However, should be able to turn off the style adaptiveness... Hmm nope, just tried turning off both adaptive and unision, I *still* get the excessive cymbal crashes on the 80s Power Rock unison style. Weird.
But the adaptive styles behave well, yes.
