OK, I watched the video. I hear quite a lot of fills that appear to have NOT been requested. And, especially in the second song, I hear fills that are NOT responding to what you play... she wasn't playing anything at all! Just asking for fills when she wanted them (and getting some when she wasn't).
To be honest, especially in the first song, I didn't feel that the 'auto' whatever it was was very musical. A crash in the middle of a verse (every four bars) seemed very distracting. Admittedly, both those songs stuck to a four or eight bar structure, so it wasn't quite as distracting as if you had had a six bar or ten bar chunk in there, but even so, it was not what I would have expected from a real drummer.
There doesn't seem to be much point in actually having a fill control if the darn thing is going to fill on you anyway!
So now, anyway, I suppose the main question is, are those pickups actually programmed into the variation loop itself (and hence not switchable at all), or are they part of the so-called 'Style Intelligence' and defeatable. Not to mention, what the hell is actually triggering them if the girl wasn't playing anything at all?
