Freezing VST instruments - No Sound

Anybody know why sometimes freezing vst instruments like Massive or Halion results in no sound playback?

The only way I can get playback back is to unfreeze?

I don’t think this has anything to do with the fact my computer is low on cpu at the same as I’m able to export a full mix fine.

Really frustrating as I need to free up cpu


Try to setup different Buffet Size (in this case a lower value could do the trick) before you freeze.
