I have got similar crashes, but without rhyme or reason. I cannot reproduce it at all, it just happens. Sometimes I’m days without an issue, other times it will crash multiple times a day. Most times it will crash Cubase as a whole stating the faulting module was Halion 4.vst3 and I have to force close Cubase or it just hard locks while the rest of my computer works. This happens while browsing for samples, as well as dragging and dropping samples from the Halion 4 Mediabay, or Halion 4 Browser into a slot in Halion 4. This never happens when dealing with the Cubase Mediabay.
99% of the time when I get the crashes, I also get these solid grey textures covering portions of the Halion 4 main window.
Thread with picture is here.
I hope you guys can figure it out. It isn’t a show stopper, but really annoying when it does happen and there is a risk of losing work if you didn’t save for awhile when this issue creeps up.
Best of luck!
