So in the past I've just used AD as a simple instrument track, not bothered with the routing of individual tracks, and bounced the MIDI track down to a single stereo audio track.  I decided that I might like some more control over the individual pieces, so when inserting AD on my latest project I selected "MIDI Source" and "All Synth Audio Outputs: Mono", as Dan Gonzalez recommended in the blog.  I then selected the output routing button on each of the AD "tracks" in the AD GUI.  As expected, I'm able to program the drums on the single MIDI track, and I can see/hear the appropriate pieces playing through their respective tracks in Sonar.  What I can't seem to do though, is RECORD the individual pieces to their associated tracks.  I thought I would just select the MIDI data, hit "Bounce to Track", and presto, each individual drum would now be it's own audio track.  But when I select "Bounce to Track", Sonar tells me that I haven't selected any audio.  I've done this hundreds of times using a simple instrument track, so I'm sure it's something simple I'm missing or forgetting, but any help would be much appreciated!

Mr Pip, I'll experiment with this issue later this evening, and report back.
 
In the meantime, here is the link to the excellent blog post describing how to set up Addictive Drums with separate outs:

Not that you need it - it sounds like you're already there.

It seems to work for me if I select (mark the track) the MIDI driver track plus the individual audio out, and select "Bounce to Track".
 
I'd have to repeat this for each of the audio output tracks, though.

you have to explicitly select the midi track and all the audio tracks. i usually just solo them to be sure. then bounce to tracks. sonar should, but does not, make the connection automatically for you.

I'm not sure why you would want to bounce to audio, but you could also just freeze the synth.

Interesting...  Did a little messing around, and freezing the MIDI track did what I wanted, i.e. created individual audio tracks of all the different kit pieces.  A few issues/questions though:
 
1)  When I selected the MIDI track and all the (still empty) audio tracks, and then selected "Bounce to Track", I was required to select a single destination track.  I don't want a single destination track; I want multiple tracks each containing the audio for a single kit piece (like it does when i freeze the MIDI track).  Any way to bounce a single MIDI track to multiple tracks, or is Freeze the correct way to do this?
 
2)  I don't really know what I expected when I selected "All Synth Outputs: Mono" on the synth insert page, but I'm only getting a Kick L track, a Snare R track, a HH L track, an Xtra R track, etc.  Most of what I've read says to select All Synth Outputs: Mono, but I'm wondering if I should be selecting Stereo. Am I missing tracks that should be receiving audio information?
 
3)  I am getting both a Left and Right track for Master, Overhead, Room, and Bus.  I'm getting no audio frozen to the Master tracks, and audio frozen only to the Overhead L, Room R, and Bus R tracks.  Overhead R, Room L, and Bus L tracks (and both Masters) are completely void of any audio after freezing.  Is this normal, or should I be doing additional routing within AD?
 
Thanks for taking the time to help out an AD (and audio routing) newbie!

In the "Bounce to Track(s)" dialog change the "Source Category" to Tracks
 
The signal from AD needs to be routed to the audio tracks. There is a down arrow at the bottom of each track strip on the AD mixer which assigns the audio to separate tracks. If this is the original version of AD refer to page 14 in the Addictive Drums Manual for detailed instructions.

May I ask again why you're bouncing in the first place? We may be solving problems that are irrelevant to what you actually want to do?

Whether bouncing or freezing, the audio routing would still need to be setup correctly.
 
There are users which prefer to bounce (and archive) rather than freeze. The explanation I have read involved accidentally thawing tracks after editing the audio. This cannot happen with bounced tracks. It is true, frozen tracks can be copied to new audio tracks to prevent accidental thawing but it may be more work than bouncing.

i've found that i don't need to bounce ad2 unless i have a really dense project with lotsa fx and plugs. i make all my adjustments in ad2 and the audio tracks as i'm mixing, then i export audible. as long as i hear what i expect, i've saved a step.
