Can you explain this or provide a repro?

Hi Noel...
 
Not sure if this is what happened to Bitflipper, but I've had some experience with a few scenarios...
 
One was where I deleted some outputs from a drum synth after they were frozen.... then unfreezing and trying to freeze again was not working...
 
Another issue I found was if outputs from the same scenario were archived and I attempted to freeze the synth it fails...
 
I hope this is some kind of help?
 

I had a freeze issue with EZD2 set to multi output. It wouldn't freeze. I had done the drum "arranging" inside of EZD2. I exported to midi file, imported midi to midi track and then EZD2 would freeze all outputs. I didn't try it in stereo mode cause,.....well, I got it to work but that would have been my next try.

I've had that happen.  I believe it is a buffer thing.  If you exit out and back in sometimes you can freeze the synth if it is the 1st thing you do.  I use to go empty the Pic Cashe folder,  but I have not had to try that fix in a long, long time.
 

May not help, but when the Freeze button (*) doesn't work, I am still able to use the drop down to freeze.

My freezing woes relate more to unfreezing a synth in an older project only to find the synth and the wave disappear. To save the day I have to undo the unfreeze. If I want to resave the project after editing it, I have to reinsert the synth and figure out what sample set I used to restore the project. ..... Or simply leave the project alone and save any edits as a new one.
 
Dimension is the most notorious offender.
 
This is why I freeze all synth tracks before closing a project.

Thanks for everyone's observations. As noted in my previous post, I did solve the problem (but neglected to update the thread title).
 
The issue was that I had an unused (and archived) audio track that used to be connected to Kontakt, but its .nki had been deleted, leaving the track orphaned. Once the unused track was deleted, SONAR happily froze the synth.
 
Thanks again to Keni for coming up with the critical clue.

I would like to make a sequel to this thread and call it...
