Is there a list?

I haven't had any problems with 9.12/13 etc until recently. I was asked to edit live recording done on a phone. To get it presentable, I had to use a lot of plugins I never use. On a one track project with a 512 buffer, I was getting frequent dropouts lasting about 5-10 seconds. Moving to 9.02 made the problem go away. Loading some older projects in 9.13 with my usual MOTU and Waves plugins worked fine.

So, at least in my case, it looks like some plugins don't play well with Pre-gen (or the other way around), although I haven't yet isolated any cuprits. I remember MOTU asking people to report such plugins. Has anyone done that, or see a list of plugins that don't pregen properly?

Slate tech support mentioned the pre-gen issue when troubleshooting recently but nothing really concrete about it. The problem I was having was Slate plug-ins 'going dead' (acting like they're bypassed when they are not).

Let's say you open a project with older (prior to current version) Slate plugins. Even though the Slate
stuff will come up in the insert slots or aux busses where you last left it, often you'll find that the plugins themselves are not processing audio, they're just passing it thru. For example, if you have an instance of VMR with a Neve EQ followed by a compressor, and you don't see the compressor meter moving during playback, then everything in that instance of VMR is "dead".

The solution, I'm sorry to say, is to remove the Slate plug-in instance and re-load a "blank" Slate
VMR, then add the modules one by one in the order you want. The Slate plugins will work again.Then, save that instance as an AU or VST user preset within DP. To check whether your saved preset will work again, delete the instance of Slate again, then re-instantiate an instance of VMR and re-load the user preset you just saved. It should work fine.

There was an older version of VMR (and some other Slate plugs, I think) that would take a long time to load if it was the first time you loaded it for the day. The most current versions of Slate plugs, including VMR, load immediately, and as far as I can tell, they all process audio immediately
and do not fall victim to the "dead plug-in" malady.

Thanks David. That's exactly what I got from Slate and specifically the issue is when you recall a saved chain of plugs in DP via the top insert slot. Like I had a good kick drum chain, saved it and called it up in another song then the Slate plugs would 'go dead'. I had to go through our whole album and replace all those individually with fresh Slate instances. That seemed to fix it but I still had it happen twice after that when I know for a fact it wasn't a saved plug-in chain. I just got done mixing and mastering our album and taking a breather so I'm not sure where the issue stands at the moment.
