Crashing using VariAudio

Hello. With CB 10 and high Sierra, I’m using an iMac Pro 2018 with 128 GB of RAM. It’s going into a waves MGB Madi interface, and finally into the Avid MTRX made by DAD via a sound grid. When I attempt to edit pitch using VariAudio, once I start shifting timing or pitch on certain notes back-and-forth, the entire program crashes and shuts down. Seemingly, I had more luck by removing the window into a separate window. But it could’ve been a coincidence. Anyone experiencing this? I can’t upgrade to version 11 even though I own it, because I need to stay on High Sierra. Thanks.


Could you try in Cubase Safe Start Mode [Disable preferences], please?

If it’s still crashing, could you attach the *.crash file, please?
