Addictive Drums 2 question

You could save much time by using AD as a VST within your project, thus saving several steps.  Program or choose your beats, and either stay in MIDI mode, or freeze or bounce your tracks.  Much quicker to do all this inside Sonar.

There's a zillion way's to use a Soft Synth drummer. 
Everybody here does it differently and for different reason. 
But the basics of it haven't changed in 30 years. 
Midi notes trigger the different pieces of a drum kit. 
You can find millions of pre made drum loops and use those
Or like me and many others, you can play the part on a midi keyboard ( or better yet a digital drum kit) and make your own parts. Just bang along using a scratch vocal, guitar and the metronome. 
I have worked that way for 30 years so for me loops take to long to build. But many are good with loops and know where to find the ones they want. It would take me all day just looking. 
 
I also have some of my old Roland 505 Drum patterns I use to start a song out with. I guess those are sort of loops. 
So welcome to the wonderful world of creating realistic drum parts. We have all the tools so there's no reason to have lame sounding drums anymore. Nobody wants to listen to a recording that uses a drum machine. 
 
Here's a cool trick.
Mike up an armchair left and right arms with 2 mikes. 
Record this to 2 mono tracks in Sonar. 
Sit in the chair and play the drums on the arms kick/snare. 
Now drag those tracks to a midi track and Melodyn will create a midi track of your drumming, A pour mans digital drum kit.
