They'd just need to be remapped to trigger AD2. and really Sonar comes with a buttload of the simpelr beats anyway for rock and blues and crap like that. kind of a hack really but I fake it well) so the other MIDIpaks did not offer anything I could not play live on my padKontrol or program. I used to play drums at an intermediate level (but self taught. I just wanted the most interesting and complex fills and beats I'd never be able to play or program myself so those seemed like the best options. For the MIDIpaks I got the Metal one, the Jazz sticks one (IIRC) and the Modern Jazz one (IIRC). I REAAAAALY wanted the Jazz Brushes and Sticks combo (which are two separate ADpaks) but figured they would not provide me with enough usage for what I'm likely to make money on. Fairfax 1 (clean, well produced kit that is good for rock but as a general up front/full bodied/punchy kit) Metal (suuuuper tight and snappy kit with triggers and all the garnish you'd expect for modern and old school metal) Indie (more vintage, less tight, more "swoosh" and "bomp" type sound, supposed to be for "indie" rock but can easily be used for "oldies" rock, big band, classic country, whatever you'd use an older kit/analog studio production for). Because I do rock/metal but often dabble in more traditional styles I went with. but all answers would likely be highly subjective. If you elaborated more on that then your query would be easier to answer. It really depends on what type of music you intend to create with them/what kind of drum sounds you like.
