I send all the individual Addictive Drum pieces to separate tracks. I already know how to use the processors I have in Sonar, and they are enough for the drums, without having to learn the ropes inside AD. Of course, you have to do
some things in AD (or whatever sampler you're using), such as drum tuning and virtual mic placement. But reverb, EQ, compression, tape simulation -- these things I do in Sonar.
