I had this problem with WL9.0.25 on the Mac. I reinstalled it and that seems to have cured the problem. Just playing a file with nothing else engaged, like plugins, would crash the program.
That must be a coincidence, because I can’t see any relationship. The crash logs shows a crash caused by some plugin (which one?) UI activity. More exactly, a software component using openGL (WaveLab does not), is causing a crash.
This could be a graphics driver issue too (but because a plugin is using openGL).
I to am having a problem with the master section in Audio Editor. I have a preset of 5 plugs saved, the first one is Slate’s VMR. If I click on that entry to edit it, I get a blank screen. If I try to just re-select VMR, WL crashes. I was able to get around it by selecting my preset, deleting the VMR in the first slot, then re-adding VMR.
Also, Slate’s FG-X loads up every time with their default preset, even tho I saved my WL master section preset to use my own custom preset within FG-X. Not sure if this is a Slate problem or a WL problem, but I don’t have these problems with Slate products when used within Logic Pro.
Have you told Slate? Slate has said they would ensure correct operation in Wavelab with the newest version FG-X (maybe not out yet?). As of November, FG-X seemed to have mouse-up problems on Mac. Don’t know if that’s fixed. Also don’t know about VMR, but it would probably be necessary to report any problems with either one also to Slate.
Even if it doesn’t happen in Logic, it’s my understanding that there can be a whole group of plugins using the same tools like JUCE that would still possibly need to be fixed on the plugin maker side, even though they work ok in other programs. That’s the impression I got from the unresolved JUCE issue anyway. I don’t know where that stands, but maybe someone else does. afaik Slate is one of the plugin makers using JUCE.
