I don't have a specific example at the moment but what I'm finding regularly is that if I freeze more than about 15 tracks at a time all loaded with VSTs and VSTis that some of the tracks will be frozen incorrectly.
One bass track I recently froze ended up being frozen into about a dozen separate media items with big silence gaps between them instead of the one single long midi media item that it started with.
Can we maybe have an option for freeze to slow down a bit so it can be more methodical as the current method is definitely producing some bugs with larger track counts frozen at once.
It's also not uncommon when I unfreeze, for the track to have the wrong preset chosen on the VSTi forcing me to put note files with these tracks so I know what preset to reset it back to. You can get some really weird sounds by having a track switch to a random preset.
Dev's please load up some tracks and do some heavier testing. If you need a project from me I'm sure I can come up with one
