Ahh... I see what was going on now.  Opening the Drum Map Manager in Preferences, Sonar created the DM1-AD2 standard map.  First time I didn't see that the 'Output' on the preset was set to my MCU-PRO.  So, of course, nothing in the MIDI track for AD2 was actually going to AD2.  Second time I did see this, and switched each note to go to Addictive Drums.  Great.  It worked as it should.  Then as I opened a different project and added the track template for AD2, no sound.  Eventually I did remember to check the output in the Drum Map Manager preset. Of course, it was back to the MCU!  So I switched them all again, and then actually remember to save the changes to the pre-set.  Dah!!
 
So it does work as it should. 
 
This maybe one more step Kamikaze may want to put into their tutorial.  Oh, and the reset to UNITY on the sliders in AD2 appears to be Ctrl-left click on my machine.  Thank you all!
 

AD2 seems to default to the first drum map in your list when you start a new project using the AD2 project template, and then you need to change to the DM1-AD2 Standard map.
 
But I almost always insert AD2 into an existing project via the track template, which routes directly to the correct map every time for me.
