Hi. Sorry if this is obvious, but have you checked the MIDI input echo on your MIDI track?
All the best.

I am not familiar with Kontakt but many times with multi out synths (like drum samplers) you have to go into the synth's "mixer" page and select the outputs to the DAW manually.
 
So just like you set the outputs from a track in Sonar to go to specific busses you need to go to the Mixer page in the synth/sampler and set the output for each channel to send to a specific output (which then gets routed out to the DAW).
 
That process then sends signal to all those individual tracks in Sonar so you can hear them.

OK - I've got a signal at the individual track levels but the MIDI notes in the track view are still invisible and when I click on a clip to bring it into the PRV, the notes are there, but they are black.  One other thing: the virtual keyboard in the PRV responds to my MIDI controller, but not to my mouse when I click on an individual piano roll note!!!

Yeah... I don't even really know what you're up to here but remember... all those tracks that you just got set up are actually audio tracks. You don't drag MIDI clips into those. There will be one track that feeds them all which is an actual MIDI track. So one MIDI track to feed all the audio tracks associated with the synth (and in Sonar those audio tracks are actually called Instrument Tracks which makes things extra confusing... lol).
 
 
If you do not have a specific MIDI track visible then try reinserting the synth/sample and make sure "MIDI Source" is selected or you could manually insert a MIDI track and route it to the synths "instrument" tracks.
 
I don't know what the "black" notes is all about.

I'm on my way out the door but just read what you said and got the "a-ha" moment: they're AUDIO tracks and NOT MIDI tracks!!!! A huge blunder on my part--thanks for mentioning it!!! I'll now go to dinner with my wife and try to keep my mind on our date and not on the project.

Thanks for your help, folks--I'll confirm success after dinner. Or the movie.

Right on. Let us know how it works out (the MIDI stuff... not the date... lol).

Hello again. Yeah, I've been meaning to switch my avatar back. The Snaggletooth image is a temporary homage to mourn ole Lemmy's passing. Very sad. I wanted to meet him before he (or I) dies but alas that won't happen. Perhaps in the "Loud Mofo's" afterlife.
 
As for at least part of your question...
 
I think what you are saying is you have generated MIDI clips for individual kitpieces instead of all on one clip. This can sometimes make it easier to edit but obviously ends up with more clips/tracks. It's preferences thing.
 
But what you would do is... if you want to retain all the clips separate (so Snare on one MIDI track, Kick on another, Hats on another, etc) you have two options (AFAIK... I don;t work like this). If each kit piece has its own MIDI clip on its own track then you just set each of those tracks to output to the synth. The synth will (or should) accept all the incoming MIDI messages then spit them out to audio tracks. Alternatively you could put them all into a single track inside Take Lanes (so each MIDI clip for each kitpiece would get its own Take Lane). Then use the "Sound On Sound" recording mode which will make it so all the clip playback and are audible (right click on the Transport Module's Record button to access these Preferences settings).
 
If you want them all on a single clip then you can just select all the clips > Right Click > Bounce to Clip(s). This will mash all the notes/clips/parts into a single MIDI clip.
 
Not sure why they are being separated out in the first place though but maybe you are tracking one piece at a time.
 
Cheers!
