I think Pragi makes valid points, Stuntpickle... everyone here is trying to help you through this frustrating situation despite the way you started.  I have had moments in the distant past where everything was blowing up for me also... but I never began a quest for help by first insulting the bakers and well, just coming off like I'd been wounded by the program or it's designers. 100 problems???
 
I've spent hundreds of hours trying to rectify problems over the years.  When all was said and done, few had anything to do with Cake... The gracious and super smart folks here on this forum are here to help but a degree of humility rather than premature finger pointing is warranted on your end; I too think your title is unjustly disrespectful.
 
FWIW, I run fairly large and complex multiple templates using Albion 1,2 and 3, Mural Ensembles, and Project Sam's OE 1 and 2.  While I have EW orchestral platinum and various NI orchestral piles of crud, I no longer use them.  My system is totally stable except for the rare instance where I get a bit crazy and start wamming too many buttons and jumping around doing too many complex things too quickly and... as things begin to freeze I always say, "why'd I do that?" knowing I shouldn't have.
 
"having a lot of problems with stability doing large orchestrals"  is a far more honest and respectful title... free of premature blaming.  And it actually describes your real situation.  BTW, you can edit your title, you know... just sayin'...

Oh, really? I was under the impression that the validity of any "point" depended upon its coherence -- something sorely lacking in the relevant post.
 
Just a hint: my own post started with a joke -- one made at my own expense. Consider: how rational would it be to incinerate someone ten times? Since each subsequent incineration beyond the first would be entirely gratuitous, the answer is "not very." However, that's precisely the sort of thing a petty person would do in a fit of angry frustration. The joke was a tacit acknowledgement of my frustration. The title of the thread was obviously jocular, but jokes tend to molder under this sort of scrutiny. Had you read my posts, you'd have noticed that I actually defended Cakewalk support -- not something typical of an outraged person.
 
Are you under the impression that the bit about the button was a literal threat? Consider for a moment that the statement conveys virtually nothing about Cakewalk staff, but rather focuses entirely on my frustration, which it renders as cartoonish and absurd. It was a figurative and self-deprecating explanation of my own unwarranted irritation. But some persons, often the objects of humor, grow to hate it as a mule does a whip.
 
I'm beginning to get the feeling I have inadvertently stumbled into one of those internet hive minds populated by some persons whose collective self worth is entirely constituted in the object of their association. Thus, any perceived criticism of the object must be met with hysterical exculpation. I mean, a surprising number of people showed up here to state -- for some implausible record -- that Sonar works flawlessly and I am personally the problem. Do they understand why I am experiencing the difficulty? No, yet they are certain I am the cause -- two disparate contentions anyone acquainted with logic would find difficult to square.
 
I am sorry if I offended you with the title of this post since I never intended to. However, I will not change the title since I cannot be compelled to action by persons who make a habit of being offended and who differ from more conventional bullies only in their timidity. At that, feel free to take offense.
 
So is this all my fault? Sure. Is Sonar entirely blameless? Sure. If there's anything else you require in order to reflect upon this issue, I concede it freely. Do you know how to fix my problem? No?
 
Then kindly stop hammering your gavel. I get it. You're a righteous do-gooder. Consider me and the world straightened out. All hail Sonar, the one true DAW!

I can confirm the picture you give of the controller ("one expression lane superimposed over the other", as you said).   I see that very frequently, and have never identified how to avoid it.   I usually fix it by re-selecting the appropriate controller using the selectors on the left in PRV controller pane. 

 I've also seen that one pretty frequently but at random points with no real rhyme or reason as to when

However when I swapped mt midi controller keybaord and USB cable the problem went away so I don't think it was a sonar problem.  I'd try swapping your USB cable on the keyboard and make sure it is plugged into a USB2 port not USB3 as that causes problems too

yikes.   this is such a typical thread.   fwiw, I don't think your video card audio, or your hardware, or "connected wandering midi", is the problem.    One thing to track down is the midi channel associated with each midi event in your tracks:    unfortunately, the way PRV works, events in multiple channels ( a valid midi thing ) in multiple tracks (a valid Sonar thing) get created very very easily.    I use the following CAL program, set to a single-character key-command in keyboard shortcuts, to re-re-re-re-rechange the controller per event to ONE channel.
 
(do
 (int new_chan 1)
 (int i 0)  ; counter, not needed if you don't care
 (getInt new_chan "New Midi Channel: " 1 16 )
  (-= new_chan 1)
 (forEachEvent
     (do
      (= Event.Chan new_chan )
     (++ i )       ; count it, delete if you don't care
     ) ; end do
  )  ; end forEachEvent
   (pause "Adjusted " i " channel events. " )   ; tell how many, delete if you don't care
)

Thanks for that.
 
As counter-intuitive as it may seem, I am restarting the project with exactly the same setup since it would probably be most useful to determine whether the issue is repeatable or just some fluke. Every attempt thus far to troubleshoot has proven fruitless, and my understanding of the parts involved is so slight as to make continued troubleshooting problematic. Unless I can repeat the issue, any fix is likely to be a false positive.

 I was not at all aware of this. I was quite sure I was plugged into a USB3 port since I have like ten of them, so with some optimism I checked the port only to find I was plugged into a USB2 port in the front of the machine. Looks like my sloth trumped my ignorance this time.

Another piece of data re audio output from display adapter:   sonar's audio configuration (Preferences -- Audio--Output Drivers)  showed no clue that it knew about the video-card's audio drivers to the audio-capable monitors.  However, when just in case I disabled sound for the video card and monitors,  Sonar popped up a dialog and asked if it should re-route audio from the video card to other outputs!  
 

It sounds like a midi routing issue to me. Sonar has had some issues in the past with plugins that generate midi. Several significant issues have since been fixed but I haven't really kept track as it doesn't come up in my workflow very often. I'm wondering if this "channel swapper" thing could have something to do with it. What does it do and why can't you live without it?

Gosh, these threads are hard to read in a coherent manner.
 
@OP, do you have any projects (even older ones) which do not use tencrazy's channel switcher to try? The "9 instances multi-timbral" stands out to me because I was having issues (with only 2) that suddenly went away with Dorchester - which update are you running?

The drivers that Sonar sees is determined by the selection of driver type, ASIO, MME, WDM/KS etc.
So until a driver type other than ASIO is selected Sonar won't see any outputs to do with a graphics card that is passing audio out though it's HDMI port. Usually a High Definition Audio driver of some sorts connected to an onboard sound chip.
When you switch from ASIO to any other driver type Sonar will ask to profile your system for sound devices. It then enumerates the various non ASIO drivers available and the bit rate and sample rates those drivers can be set to. Hope that helps. Lots more no on this subject but I don't have the time to go into too much detail now.
