So I'm just curious how others are setting up AD2 in their projects.  Do you do as much as you can within AD2 and just bounce the stereo output or do you set up a multi-output instance and do all the processing in Sonar?
 
I seem to be getting inconsistent results with just freezing and am looking into other possible ways to go about this.
 
I'd like to see what others do and why.

Multi output all the way just gives me more flexibility and I'm happy using the plugins I know well for processing

Every kit piece, overhead, room to their own track  ... then process, group, route inside of SPLAT ... that being said, I would also like to hear the input of many others ... great thread to get started! If theres a better way, I am in.

Everything switched off in AD2. Kick, snare, hats, tom1, tom2, etc, flexi1, fle2 etc all mono, Room and over head are stereo (No Bus). I remove all the bleed from the other kit pieces to the overheadz, so it just cymbals. I can then re-introduce later. I group the Toms, in Sonar and hide 3 of them after a touch of panning. So it's basically all coming out clean, and into Sonar.
 
I still have to use the AD2 interface for kick drum front and back  and snare top and bottom balance.  Also tuning drums, which I don't really play enough with.
 
I prefer to have an overall set of reverbs in Sonar doing that work. As I mix up all the kits, they all have different Room mic results from being recorded in different studios. So I'm still don't have a clear idea what to do about this, so it''s just messing with it. 
 

As a rule I use my own VSTs for this. I use BFD 3 that has great processing. As the others have pointed out each drum to its own track.  I have one particular VST that I like very much on the drum buss. Its the Nomad Factory Studio Channel SC-226. I will also use various plugins depending on what sound I'm after. Don't forget EQ. 
 
I do think all this can be done with the built in processors of the drum sample players but I find it easier to get the sound I'm looking for using the plugins I have. 
 
 
I believe that this is great question that needs very thoughtful answers. So far I think you have got them.

Depends.
 
If I want a quick, processed and ready to go drum sound, I'll just dial up one of BFD's many presets and just bring the main stereo pair into SONAR
 
But with the majority of my songs I'll split each kit piece out to it's own track in SONAR and do my own processing
More often than not I'll go even further and have separate tracks for Kick In, Kick Out, Snare Top, Snare Bottom etc

Hi, I usually operate in a mixed mode kinda way.
 
I'll set AD to separate outs for all tracks but use certain aspects of the AD processing on individual kit pieces. I like the distortion and tape drive settings within AD and will usually apply some of these. I'll also send the AD reverb to the master out and mess around with this in SONAR such as parallel processing with a compressor etc.
 
For example, I'm using Acustica Pink on my snare, overheads, room and master drum bus within SONAR, but apply a little crunch within AD or even use some of AD's compressor on kit pieces.
 
Works well here. 

I am not an Addictive Drums user, but the principles apply to any drum sampler that offers full-featured in-the-plugin mixing: I have two track templates, one that routes everything to the primary stereo output and another that implements 5 separate outputs for kick, snare, toms, hats and overheads. Kick and snare always mono.
 
I tend to use the sampler's own EQ, compression and transient-shaping effects so they can be frozen along with the drum tracks, but leave all other effects to SONAR's fx bin. Two reasons. First, reverb - I'm an old-school guy who thinks reverb should make all instruments sound like they're in the same room. They should therefore all share a common reverb bus except when the reverb is used as a special effect. Second, most other effects (delay, distortion, phaser) are things I'm likely to tweak/substitute/remove right up to the final stages of the mix, even if the drums have been frozen.

I'm in the minority and do all processing within the VST, whether it's AD2 or NI Drummer series, just because I want fewer tracks and fewer plugins in the project. Although AD2 isn't as wonderful sound-wise as NI Drummer series or SSD4 (or BFD3 which I don't have), if you tweak and process it properly it sounds quite good. Good enough for songwriters (including me) at least.

That's my workflow.
