I spent a bunch of time on AD2 last night and feel like I'm finally understanding how to make a ride sound like I want. It has been a learning curve for me, whereas other drum software just gets me the right sound automatically (if I pick a good one).
The difference, however, is that with AD2 you can really, really tweak the sound, whereas other ones I've been using give just one sound. So AD2 impresses me a lot. But it's been a learning curve experience. It has a lot of adjustments possible around velocity sensitivity etc.
