Hi
I've had Decent Sampler (latest; 1.7.10) causing Cubase Pro 12 (latest; 12.0.52) to crash horribly with a "save your work and restart Cubase" error. It's done it twice now, seemingly when trying to load a new instrument. Cubase also doesn't shut down cleanly, it sits with a rapidly increasing memory usage until I kill the process. The same instrument then loads ok after a restart of Cubase. This is on Windows 10.
Cubase crash dumps are here and here if they shed any light on the matter.
