I usually use Charlie.
So you got:
Timing Vary
Power Vary
Snare Vary
Hihat Vary
Then over in the song you can vary timing and shuffle in each part or in the song as a whole. (how do timing in the brain and in the song interact?)
I know you can also do stuff with midi and audio jam but that is beyond me.
I play around with the settings but really don't know what I'm doing. I'm just randomly turning stuff.
So how do you best simulate a "loose' drummer banging away in your garage?
I guess I'm trying to develop your typical local mediocre drummer who is sloppy but groovy and has flashes of brillance after a few beers model.
Thanks
