How to? Insert silence ..

Simple question, I hope -- how to add a few seconds silence at the end of an audio clip?
 
I make audio tracks by running a bunch of midi tracks through a bunch of VSTs (kontakt).     Frequently I want to work with a section, rendered using "bounce to tracks ".     But then I want to modify that audio 'clip' by inserting a few seconds of silence at the end of it, so that I can use the underlying audio file and not have an abrupt ending.    I can't just make the bounce selection longer, in some cases, since the music continues with material not wanted in the selection.     In order to add silence I've been calling up an external sound editor just for this little purpose ... surely there's a way within sonar? 
 
[edit]
btw, dragging out the end of the clip, hitting just the right spot and finding the blue bar, makes it appear that there is silence at the end, but it isn't saved into the audio file ... I suppose one could rebounce that clip, dragged out, into yet another clip .. but again there is probably a better way.
 

I usually just drag the last played clip out for what ever time I need.  I find this very helpful when the last playing clip is midi which allows the synth time to play out the note with proper fade.
 
Hope this helps.

Dragging the clip out, then using "bounce to clips" on that dragged-out clip works, but then I get yet another audio file to wade through (just did it .... #400 from this one project).     What I'm seeking, I guess, is a destructive edit of a clip's audio file ...
 

Have you tried dragging out the length of your midi tracks prior to rendering?

Thanks Charles, I'll take a look.   
 
Perhaps I'm not clear, having again gotten a suggestion to extend the midi clip:  this is for work in the middle of a project, the midi stuff goes on and on but for the moment I want a rendering only of a certain portion.   And I'm not concerned with preserving reverb trails or anything like that ... just want to do what I said: add silence at the end of an audio track, and do it fast. 
 
Anything that involves 're-bouncing' the resulting audio is necessarily a many-second process ... while in samplitude, just for instance, I can "insert silence" with a simple click ... half a second and it's done.   And of course, recording the silence in real time, then adding it to a clip, then re-bouncing ... sure it will work, but the time commitment is long enough that I would get distracted and come to the forum here and ask how to do it. 
 

I thought of this, then tried something.
I enable a 'volume automation', then dragged the 'end node'; a quick bounce to clips and its done.
If SammyTude does it better then Steph Curry should not have been the NBA's MVP. Win or loose, King James still the better, and so is Sonar...........

Thanks for the ideas.   I guess I'll get used to the extra render, not that big a deal.  
 
As to your last question, why, brundlefly, it's actually a workaround for another software creation:  the way soundcloud works, anyone who listens to this wip track that ends suddenly will suddenly get started in a soundcloud recommended track ... and if you know how soundcloud works these days, that's a thing to protect your listeners from!    So I always add enough silence to give an alert listener time to hit the off button.

This Soundcloud thing has been bumming me for some time now. I searched for a way to turn it off within Soundcloud (YouTube lets you turn theirs off), but no dice. It makes me not want to go to the Sonar "Songs" forum. Thank you, William Copper, for caring enough to look for a solution.

Here is a way to insert silence in Cakewalk Sonar Artist.   Locate the beginning and end of the section to silence.  Highlight that section like for a cut and paste but don't cut and paste.  Instead got the Process -> Audio Effect -> Audio Effects.  On the "Gain" sliders reduce the gain in that section to 0 (zero).  Bang Zoom section is muted but not gone.
