The most obvious reason to prevent loop back is to save our speakers and our ears from feedback.

Hey sharke: Is there a way for a person to second (i.e. increment..FR++) the FR? Does it take a FR number? If not I'll go submit one also. I think it sounds like solid idea. Regards,

I don't think it gives you a reference number. However I should imagine all submissions are categorized and the more popular ones are given more weight.

It should be available and I hope they make it standard in future versions. Studio One can do it now in their latest update. Buses can be routed to any track input and it is handy for several reasons.
 
Some VST synths do not repeat themselves with the same midi data and it is in this situation it is very handy. Patching external cables is one way of doing it but it can be done internally. It is dangerous but common sense has to prevail in this situation.
 
It is nice too to bounce an entire mix ITB and have the option of being able to tweak faders on the fly too. I didn't think I would use it but once I got it, I have, and it has been very worthwhile.

Anyone urgently wanting to record softsynth audio output on the scale of maybe a track at a time could try this workaround that uses real time bounce.

That's an interesting workaround...I could sort of get it to work, the problem being is that sometimes your "performance" involves elements of the VSTi's GUI which can't be controlled with a controller. And when Sonar is bouncing, you cannot access the GUI.

Rats!

It would be nice if SONAR had the option to record a softsynth to audio in real time.  I have a Saffire 24 Pro (DSP) which allows me to insert a virtual loop back into SONAR.  That is how I am able to record a softsynth's audio output on the fly (capturing real time playback as audio).  I specifically shopped for an interface/soundcard that had this specific functionality.   So, you can say, 'why doesn't my soundcard have a virtual loopback?'

I've wanted this function numerous times, and its REALLY annoying that its not possible from within Sonar (as it is with several other DAWS eg Ableton, Cubase).   I wanted for example to record the output of Stylus RMX when its playing back live a 8 channel multi - so there is NO MIDI in this case, and its a right pain to make 8 midi tracks in Sonar and route them to Stylus RMX channels, then pull over the midi from Stylus onto each track.  Anyone who has tied that will know what I mean.  I just wanted to press record and catch it.

Saffire 24 Pro has a loopback which allows this?  How does that work in Sonar - what is the process setting up the necessary tracks?

Perhaps it's done to avoid feedback loops or something?
 
I just plumb an ASIO out channel back into an ASIO in channel on the soundcard to do this.  Makes it easy to set up dub-style feedback loops too (Craig Anderton does a similar thing he calls a 'looper' in his X1 video).
 
I usually record a mix in this manner too - perhaps it's a bit old fashioned of me, but I feel more comfortable playing the entire piece through in real-time and recording the master bus back into a stereo audio track as opposed to the 'export' type function.
