I erroneously thought the POST button in console view or inspector SENDS module would send the track's signal After or Before the FX module.    Seems that it doesn't, rather has to do with before or after the faders. 
 
So:   how do I route a track's signal very simply in two parts:  part 1, a reverb tailored just for that track and part 2, the same signal without any per-track reverb sent to an Aux reverb for an ambiance that is similar for a group of tracks?   I'm sure it's another dumb question, but having finally realized I've been reverbing a reverb, I'd like to improve. 
 
If it matters, this is an Instrument track (one of the outputs from Kontakt, VSTi).

From What I understand what you are saying, You would set up 2 busses, first one would be for the reverb exclusively for that track and you would set up a post fader send from that track to this reverb, Then for point 2 you have another buss and have your ambiance reverb set up on it, and you can send the tracks you like (post Fader) to this buss at varying amounts, including the track which was sent to the other reverb.
Not sure how applicable this would be but I've done some videos relating to this on my youtube channel. See my signature for the link and go to 'My 3 reverb set-up' playlist on the channel.

Thanks for the info, and I'll check out your video channels.   But what you seem to be saying is that to get a "per-track" reverb I'd need another bus for every track?   That would add up to a lot of buses!  
 

Good stuff.....like your vid ....thanks for info .

Not unexpectedly this has been discussed before: here's a brief thread,  http://forum.cakewalk.com/Sends-and-busses-and-things-m3319362.aspx#3319362
 
For orchestral work, I like the "Virtual Sound Stage" plugin, which I've been using on many instrument tracks in order to place different instruments in different places --- but that seems to be defeating the attempt to also run each instrument's sound into an overall ambiant reverb on an Aux bus, since that Aux reverb, it turns out, is reverbing the output from VSS plugin as well as the original dry signal.   
 
More ideas welcome. 

Thinking this might be a job for "Patch Point" I tried to insert one on an instrument track:  immediate crash.
 
 

Ok so using two aux tracks seems to work, with no inserts in the main instrument track, the volume fader turned all the way to zero, one aux track having the per track reverb at full send level and the other holding an ambiant reverb at a reduced send level, grouping together many tracks.   
 
Seems like it would be so easy to have all the per-track stuff ordered in any way you choose, so that a send could come before an FX entry ... but what do I know.

I used to assume that too originally. It would be useful if it worked that way.

you can do that using parrallel processing, for example make a copy of the track and send this dry track to the reverb and blend it in with the processed track.

Are you saying that you normally use a separate reverb for each track? I would advise against that unless you're going for something very specific like a disjointed spatial image.
