Mysterious silence/"muting" across multiple channels of a project--help?

Hey Sean, have you tried restarting the PC? Just kidding man. So I'm not known to be capable of offering advice around here and hopefully someone with far more experience will help you, but I have a suggestion based on my own experience. First though, is that SPLAT or CbB? It's possible that that Cakewalk session got corrupted somehow somewhere w/ the busses "connections" as it were or something else, as this happens to me w/ CbB now and again, where I have the time line glitch when I press space bar to stop and it will just hang for 3 seconds before rewinding and the only way to fix it is to port the contents of the session into a clean new session. I've gotten to where I deleted absolutely everything (tracks, plugs, instr) in the session and still the glitch remains and only a clean new session fixes it, and then sometimes an aux which was previously working just stops working properly for no reason. I know this isn't your specific problem but what I think *may* be happening is an inexplicable corruption within your Cakewalk session somewhere.

This is just what I'd try and have done w/ success:
For the buses that you think to have this problem first take note of your plugs and settings on them then try reinstantiating those buses. But the problem may broader than just w/ the busses...

So what I usually do when things get messed up for no reason and I lose confidence in the session's stability is I highlight *every single thing* in the session on the track view *and* the busses in console view and all instruments - the whole darn session - and I save the whole lot as a template. Then I open a clean new blank session, load in the template and bam, there goes my whole previous session ported over to the new clean Cakewalk session. It's easy to do and no real risk and thus far it's worked for me every time.

Oh and this project was starter on Sonar Platinum and is now in CWBBL. Haven't tried bringing it back into SPlat yet!

Have you tried starting a new project, then dragging your existing project into the your new one via the Media Browser?
 
It sounds like your project has somehow got corrupted, so maybe importing the tracks via the Media Browser might help to sort it out.
 
I've used this method to successfully sort out issues with projects created with much earlier versions of Sonar.

Hello Mark!

Thanks for the suggestion. Importing via the Media Browser does indeed work! However, then I've lost what is otherwise a finished, very complicated mix. I don't suppose you have any other ideas along these lines?
 
Hello Dan!
 
Thanks for the suggestion. It's a good one! Unfortunately, it didn't change anything in this case.
 
Man, starting to thing I might need to face up to the inevitable total remix @_@

Right on plus I was just coming back to tell you to try the duplicate track trick 😁. I have the corrupted session thing happen for me in CbB like 1 in 20, which is lame and as I've used cakewalk exclusively since pro 8 and I've no idea if other daws behave this way(?) So this thread could be helpful to me at some point unfortunately
