It's like clock work.
 
only when I open it in PRV. I can bounce it to tracks, but if I try to open it in PRV, Sonar crashes.
 
I tried
- changing the output of the track
- sneaking up on it from behind (joke)
- reimporting the track from a backup (midi)
- I was able to stretch the clip beyond it's end
- bounce to clips
- moving the now time to a different part of the clip
- rebooting pc
 
Feeling stuck. Anyone experienced anything like this?
 

ptogram changes or automation in it?? did you try replacing the synth its outputting to?

Try opening it in the Event List and look at what it contains. 

I split the clip at the end and deleted the end of the clip. Then I re-created it. That's got me working again. Thanks for your posts.

I didn't think to check the event list, John. That was a good idea I didn't get to.

Swamptooth, there is automation on the synth, so yes, I tried setting the output to my alphatrack (figured it was innocuous haha). I didn't see a null output setting for the midi track. In anycase, it still crashed.

omg it did it again!

I have deleted all non-note items from the midi track to be safe.

I am going to hit save every 3 seconds.

I don't know what's up.

btw, this is a midi track I downloaded from some website, so that's probably the problem. My kid said she wanted to sing some Xmas songs so I downloaded some midi files as a starting place. Thanks for the help!

Which synth are you using for the Midi?

Haven't seen any problems so far with CC data in the PRV - so far the only thing is program changes. I've been doing a lot of orchestral stuff with heavy CC usage. There's always a possibility that there may be other trip-ups in the stream... 

CW development is aware of this problem.

Thanks guys! It is using a Dimension Pro Synth.

Swamptooth, it did have program changes in it that I removed.
