Loud POP Then Progressively Louder Static and Crash - [Resolved]

OK, I have a new project that I have barely worked on which seems to have a major problem already:
 
I can no longer work on the project for more than a minute or two before I hear a loud static-pop through my speakers and then major digital noise starts feeding through my speakers at which point I have to quickly exit Sonar.  It is kind of like major digital clipping that seems to happen for no reason.  When this happens I have noticed that the VU meter for Session Drummer spikes to 99 db and shows completely red which does not clear until I close the program.
 
I have seen this before in Sonar X2, but it was rare and I'm not sure if it is related to Session Drummer or not.
 
Has anyone else had this problem?  Does anyone know what could be the problem?
 
I think I may have to scrap this project, start another and hope this doesn't keep happening.
 
 

Something similar happens to me when I time stretch a few audio clips.
 

edit: have to update my sig, 32gigs of ram

Ahh, I think there are a couple of things for me to try:  I was playing with stretching audio in this project and I will try reinstalling my drivers.
 
 

I am wondering if it does have something to do with my MOTU, but I will try reinstalling the drivers, hopefully it isn't related to the stretching of clips, because that is handy.

Did you "Bounce To Clips" after stretching?
 
I've had similar popping issues after an edit or adjusting Audio Snap and and bouncing the track helped.
 
Good luck!

Ok, something is majorly wrong with Sonar now - I started a new project with only MicroTonic and Diva running and out of nowhere I got an nddll.dll error and Sonar crashed.  Now Sonar crashes upon starting every time, even with projects that were completely stable just days ago.
 
I am going to reinstall my MOTU drivers and if that doesn't work, Sonar.  This is frustrating!

Ok, I wasn't able to uninstall the MOTU driver, however I was able to reinstall an older version of the driver from August and now I am able to load previously stable projects.
 
The new project I started tonight, which has Microtonic and Diva in MIDI tracks only crashes Sonar upon start-up!  I guess one of them needs to be reinstalled.  I'll try that next.

I don't know if the problem with DIVA is related to the pop problem I was having before, but it could have been the MOTU driver or the time stretching I was doing.  I hope I don't see this problem again.

Not sure how to prevent it but to protect yourself and your system, insert a limiter on whatever bus your loops preview through.

Hello and thanks, I doubt that will help, but I will surely try. I notice that this problem is most prevalent with a heavier project. One that has 50+ tracks etc... and when some of these have many take lanes....not sure if that is the catalyst or not. In either case, this is surely a worrisome problem that should have been addressed by Cakewalk earlier on.

Might have been better to start a new thread.  You added on to an old one that has "Resolved" in the title, which will likely discourage viewers from reading.
 
Please create a signature and list your system specs (See mine for example); it'll make troubleshooting easier for us. Also, I recommend the free Ice9 Automute plugin for stopping overs.  Like Jonesey said, you put it at the end of whatever bus you're using.

Hello JonD thanks!
 
Just thought I would share this, after MUCH MUCH pain and countless hours of total frustration! I have found my problem and would like to share this; hoping that others could
a: simulate the problem
b: avoid it if it does happen.
 
Believe it or not it was a plugin! The plugin is Soneq. I am saddeed by this, as I LOVE the way it sounds. Does wonders for BD.
 
I tested thoroughly and under various scenarios so as to duplicate the loud POPS and eliminate other factors.
 
I would experience a SUPER LOUD POP when I had a loop running. At the end of the loop, regardless of loop duration, I would get a loud pop when the sequence ends and then as it resumes, it would take moments for the audio engine to reinitialize.
 
I made sure that I installed the plugin in the correct 32bit directory.
 
I was careful to rule out material-being-played; as I was able to simulate the pop on various busses that had different program material.
 
I wrote to the company with provided details as to how I was experiencing the POP.
 
I am ever thankful to JonD and Bristol for guiding me to the ICE9, thank you! Its a lifesaver!
 
I will keep this panel up to date on whatever comms I receive from the plugin company...
 

Hello All,
I should mention that although the plugin insert caused the pops and removal of plugin stopped them....it may not be the plugin but rather a process by which this particular plugin was susceptible to the pops.
 
I have also asked MOTU to check into this as I also am experiencing some other freezes where the speaker output is like digital distortion (loud) and Sonar freezes, the only way to stop this is to reboot the audio interface.
