Simple sound on sound question

I am running sonar Jan 2017.
I want to loop and record, where each loop is immediately audible so I can play over it.  This is so I can switch instruments in a live situation and play over the prior tracks (like a looper).   According to the help file, I should be able to immediately here the prior loop(s) if I use the sound on sound mode.  However, it is silent.  If I stop and rewind, it is all there and playing back, but I want to do this on looping.  Am I missing something?  Help is greatly appreciated.  

If you want to do audio looping try Mobius.

Have you tried unchecking "Create new lanes on overlap" ?

If you don't need every loop (take) in its own lane than give this a shot.

It works, I have used it many times.

If you are recording midi, each instrument has to be on a separate channel, not omni.

The audio sound on sound has never worked like a looper when I have tried it.
 
The reference guide says
 

Thanks, but what I want is to hear the previous pass(es) as I record.  In other words, use it as a looper.  I would have thought that such a simple capability would be available.

Oh, them un-select Comping and just select Sound on Sound
 
Select these options:
 
Sound on Sound
Store Takes Lanes in Separate Tracks
Create New Lanes on Overlap
New Take Lanes on Top
Do not Group Tracks
 
Once this is configured, I save the project and then close and re-open the project. (May not be needed, but that's just me.)
 
I select the desired loop points. 
I insert my Soft Synth
Arm the track and begin playing the synth.
On each loop pass, I only hear the part that I an playing and the previous parts played are in take lanes.

PS: Selecting sound-on-sound does NOT work.  I still have to stop and restart to here loop 1, otherwise I hear only what I am recording (loop 2) without loop 1.  I tried autopunch with "mute previous tracks" deselected as well; still no luck.  I have tried just about every permutation of options in the recording dialogue box.  Perhaps there is something I need to set elsewhere?  
 

Well, glad to know that it is confirmed.  I'll call them and see what they say.

SONAR isn't designed for live performance-style looping. However TH3 has a looper, and while I haven't tried the following, you may be able to set it up in an Aux bus. Then when you want a specific instrument to feed it, turn up that track's Aux Send and loop it within TH3.
 
I can't think of any DAWs offhand that does live looping by itself. Ableton Live started including a Looper plug-in around version 7 or 8, so you might want to take a cue from them - I think the plug-in approach (e.g., the free Mobius one mentioned earlier) is probably your best bet.
 
I've done looping in SONAR without recording per see by feeding a plug-in delay's output set for a long delay time back into SONAR using the external insert. However then you have the usual old-school looping problem of what happens when there's not enough signal to feed back any more.
