Session drummer 3

 Pretty close, Steve. SD2 actually only shows a mixer view. The numbers below the drum icons correspond to the output track. By default, they are all set to output 1. In SD2, click on the number, and use your mouse wheel to scroll through the outputs. Same idea, just a different approach between SD2 and SD3.
 
Agentcalm, if you could buy SD3 separately, it would probably be around $100.
As a registered Sonar user, you can upgrade to X3Studio for $99 until Oct 31.
I just did, and SD3 was a factor in that, among other plusses.
As Steve noted, you have essentially the same functions in both, but I like the sampled drums included with SD3 a little better. That said, I've been running SD2 & 3 side by side for some interesting textures.

And you can load any sample in the tam and cowbell slots; they don't have to be what the icon shows.

Agent.  My apologies for not explaining i was not using "overhead mics" literally.  I meant you could route your virtual instruments as if they were all be recorded from overhead mics. A sample setup would be something like this:
 
Session Drummer 2 Kick routed to channel 1
Session Drummer 2 Snare routed to channel 2
Session Drummer 2 high hats routed to channel 3
Session Drummer 2 Low Tom routed to channel 4
Session Drummer 2  Mid Tom routed to channel 4
Session Drummer 2  High Tom routed to channel 4
Session Drummer 2  Crash Cymbal routed to channel 5
Session Drummer 2  Ride Cymbal routed to channel 5
That still leaves three outputs for percussion or other sounds.  You could easily assign the high hats to the same channel as the cymbals if you needed another free channel
 
Create Buss for Kick, Snare, Overhead, Drum master respectively
 
Since kicks and snares are the most likely to be reinforced with layering, the individual busses leave room for that sort of thing.  Route the other channels to overhead.  The idea here is to simulate a typical overhead mic setup but with a lot more control pre-buss than one would have if you were using actual overhead mics. having a reverb on this buss and or send from a reverb buss helps sell this. Using channel tools to control width on this buss  Route all of these busses to drum master so you can have one master fader for drums to mix with other tracks in your song.
 
Needless to say this is one of many ways to go about this.  One could also toss in a buss for parallel compression or create a buss with a convolution reverb to simulate a room mice capturing it all and then routed to drum master buss as well.
