Solved: Session Drummer 3 Pattern won't play in track

I'm trying to get familiar with Session Drummer 3 for projects.  I've watched a number of videos and have what I think is a simple problem I can't solve.
 
1.  I start a new project.
2.  I create a new track by adding Session Drummer 3.
3.  I can load a kit and listen to the patterns within the SD3 interface.  I can hear the pattern play and the level meter bounces in the track
4.  I select a pattern and drag it to the track in my project.
5.  When I attempt to play the pattern in the project track, there is no audio.  There's no activity in the level meter.
 
What's the difference between playing a pattern within SD3 and playing that same pattern in a track in a project?
 
Thanks in advance for your help. 

Thanks, Robert.  I dragged it to the synth track, not the MIDI track.  Putting it in the MIDI track works as advertised.  

There may be confusion over the difference between a "Simple Instrument Track" and the "Synth Audio output" options. A Simple Instrument Track is a hybrid containing both an audio and MIDI track. Had this been used for SD3, dragging the MIDI loop into the track would have worked. When using one of the three Synth Audio Output options, there needs to be a MIDI source because the Synth Audio Output options are only audio tracks. The reason the loops played inside SD3 but not when dragged to the "synth track" is the synth track was an audio track. SONAR will allow MIDI data to be dropped into an audio track but it will not play.
