I've had so much trouble with Native Instruments stuff in Sonar it's unreal. The two just do NOT play nice. Way too many issues to mention....
 
But the latest one is the last straw. Now the mixer in Native Instruments Drummer libraries (70's Drummer, 80's Drummer etc) won't work properly. There are tabs for kick, snare, toms etc. Obviously, these tabs are supposed to act like radio buttons (i.e. only one can be selected) so that you can access the mixer and output settings for each drum. But all of a sudden, I'm able to select multiple drums at once in the mixer, and the settings in the settings pane below don't change according to the drums I'm clicking. This pic shows the problem:
 

 
Note how all of the drums are selected except TOM3. You should only be able to select one at a time. Also, notice how both "KIT MICS" and "BUSES" are selected in the top right - again, these should act as radio buttons. The settings in the setting pane below the drum tabs don't change when I click on a drum tab, so basically it's impossible to configure each drum. The whole thing is screwed in Sonar. 
 
I tried loading the same libraries in both Reaper and Pro Tools and it all works perfectly. 
 
This is a problem that has just arisen - I was using this same mixer just a couple of days ago without problems. This is characteristic of all the problems I've had with NI stuff in Sonar, one minute everything's fine and the next minute a whole host of debilitating issues appear from nowhere. I cannot work like this any more! Neither NI or Cakewalk seem to have an answer.  

I have had Sonar forever, and NI Komplete stuff as far back as Komplete 3, and am on Komplete 8 Ultimate at the moment, and have not had any particular issues between Sonar and NI.
 
I do have these components that you refer to above, and I will see if I can get them to exhibit behavior similar to what you are experiencing.
 
It's going to be a couple of hours, but I will post back with or without the issues cropping up on my system.

Thanks Bob. This particular issue is not something I've seen before, I just noticed it today. I've tried resetting VST plugins and rescanning etc....and I've also tried all variations of Kontakt (8 out, 16 out etc) - nothing fixes it. 

sharke: I'm not seeing that in my Studio Drummer in NI (Komplete 9 Ult.). I know you said 70s Drummer et al but the Studio Drummer looks identical in appearance to what you show. The only 70s, 80s stuff I have is the Abbey Road series.
 
You state this is a new problem, has anything changed on your system? How are you selecting the tabs? I tried <Shift> and <Cntl><Click> but could still only select one tab. It may sound dumb but when I first saw your graphic I thought that Tom 3 was the selected piece (IOW: the graphics had been reversed).
 
I have to admit I've had problems routing stuff out in Kontakt previously but I ultimately traced in down to my error...not assigning stereo/mono correctly.

Nothing's changed on my system and I haven't screwed with any plugin settings in the plugin manager or anything like that. It was working fine a couple of days ago, then today bam it's all gone pear shaped. I'm just selecting the tabs the same as you, by clicking on them. Instead of acting like radio buttons, they toggle on/off and I can turn all of them on. The settings in the setting pane seem to be stuck on the kick settings. 
 
It's the same with all of NI's Drummer series: 60's/70's/80's/Modern/Studio. And everything works fine in Pro Tools and Reaper. 

My apologies for STILL not being back at my own computer (I am repairing 7 computers today).
 
Is there any chance you are seeing differences because there are TWO series of Abbey Road libraries and applications?
 
There are the Abbey Road Drums, AND a separate Abbey Road DRUMMER series, both have 70's, 80's, etc.
 
PERHAPS these work differently and you have loaded the same decade (70's, for example), but possibly using TWO different synths and sets of sounds?  (again, there is an Abbey Road 70's DRUMS and an Abbey Road 70's DRUMMER synth and library).
 
Just wondering - while I am trying to rid myself of these cursed computers so I can get back to recording some progressive rock tracks.

What Bob said sounds like a potential, also, does this occur in all projects or just one? Can you start a new project and insert the player and library with the same result? Given your response in PT and Reaper if you can open it in a new X2 project that would point to a project problem. I know that doesn't solve the issue but I'm just trying to narrow it down.

Yeah it's definitely the Drummer series as opposed to the "Drums" series. I believe the Drums libraries have a totally different looking inboard mixer with much less functionality than the Drummer mixers, and they look totally different.

It happens when I open a new project in Sonar. I also forgot to mention that it works fine in standalone mode.

What you describe is typical of all my Sonar problems. It worked yesterday and today it's toast. I can't replicate your problem on my system and that's also part of the Sonar trip. It seems that their are unique problems to deal with that can't be replicated on other systems. It sucks, but you're far from alone.
