Inspector>Midi>Time+ (aka "track delay")
Sonar gives it in Ticks and Milliseconds. I normally adjust the timing of strings, organs or vocal choir synths within the synth plugin itself. Most synths I use has a negative and positive attack knob for this - Xpand is a great example.
Oh the "buffer" For some reason I thought you said Tempo. Had to read again.
Launch Sonar.

You know you're in the Sonar forum, right?
This is Sonar's Track Control Manager window - where you can choose whatever you'd like to see on your tracks in the track view.
My portal setup:
Dell Latitude 8th gen i5, 16GB Ram,
Maudio Airhub Interface - USB
Samson C03U - USB
Beats by Dre headphones - USB
MPK Mini Plus 37 keys - USB
I don't actually need the Airhub, but I want the extra boost for the headphones. No hassle at all.
Route the output within addictive drums to a number - create an audio track in the daw and route its Input to the output number within Addictive Drums.
