Not looking for opinions as to whether to try.  I just purchased the D-Box.  
 
I am looking for Sonar specific information vis-a-vis the d-box.  I have watched the Cubase and Logic videos.  They are similar to Sonar in enough ways that I think I understand track selection, bus routing... But I want to make sure.  
 
I have the video about setting up the D&Apollo 
 
Thanks in advance for any guidance.  

I used to run Sonar to a Neve 8816 summing Mixer by running 8 stereo busses, like Drums, Bass, Keys, Lead Vocals etc. directly into it. The trick was finding the right amount of gain to 'push' the summing Mixer a bit. The Neve would naturally smooth out some of the transients when hit harder. As someone else said here, I would mix right into the summing mixer in the first place, not just finish a whole mix and sum it later.
