[Solved] Playing Soft Synths in X3

Folks, I apologize at the beginning for the very simple nature of my question buy I've spent two days watching videos, reading Scott Garrigus' book and Cakewalk documentation but I'm still stuck.  I have lots of experience recording live audio with Sonar but I have yet to be able to record using soft synths.
 
I feel like I'm following the directions but have yet to hear a sound when I play my MIDI keyboard.  Here's a screen capture of my current status.  My basic audio path is good because when I play the project, I hear the audio track (Track 1) loud and clear.
 
As you can see from the capture, Sonar is recognizing my MIDI signals as the level meters on Track 3 bounce when I play the keyboard.  But there is no corresponding movement of the meters on Track 2 and no audio is produced.
 

 
Thanks in advance for your patience with my basic problem but it's been kicking my butt and I want to actually be able to create something.
 

Hey, John.  Thanks for the prompt reply.
 
Dimension Pro.  (Were you able to see my screenshot?)

Load TTs-1 as it's a easy one to use. It will default to a piano for all channels and drums for CH 10. 
Open the tts-1 GUI mixer and click on the pre view icons at the bottom of each channel. This will confirm your synth has a output as it plays little snippets of the sound chosen.
If you hear nothing make sure the TTS-1 output is assigned to your master output.  
Make sure the midi track your triggering has it's output assigned to the tts-1 

I'll try another way to share my screenshot:  https://www.flickr.com/photos/129172854@N08/15507013217/
 
scook:  When I opened DimPro, I selected an acoustic bass patch.  (If I maximize the DimPro window, the patch (Full Acoustic) is displayed in the "Program Browser" field.
 
johnnyV, I loaded the TTS-1 and, BAM!, I instantly had a track the I could hear!
 
I'm going to add my DimPro track back and compare the settings to try find out what's different.

+1, Dimension Pro can have sounds assigned to only certain keys and does not visually show you which are not mapped. For initial routing checks, a piano is best to use to check your setup (all keys will have a sound assigned to them).

It could be a routing issue, except for the synth the routing is the same for TTS-1, Dimension LE and DimPro. Does the stand alone DimPro play correctly?

Make sure that the "input" of the audio track (in your stated case, track two) is set to DimPro, channel 1 and the "output" is set to either the main bus or your main audio outs.
 
You might also try loading an instance of DimPro and choosing "Instrument Track" instead of breaking the instance into two tracks (midi and audio).  With everything in one track, X3 should set everything to your default midi/audio gear...

Glad you got it resolved. Please edit the subject in the original post and add [Solved] to the subject. This helps everyone know the issue is resolved and aids when searching for solutions.

Alls well that ends well!
