I am working on a really big project (100+ channels) and using a ton of plugins. So, this could be a reason for Cubase to become unstable and also the reason why I can’t include steps to reproduce the issue.
But, the particular action that these days crashes my Cubase on regular basis is when I hit a key command (in my case “R”) in order to open Sampler Control in the lower zone. When I hit that command in let’s say 1 out of 10 cases Cubase will just vanish. This doesn’t happen in smaller projects.
Version: Cubase 9.0.10
MacBook Pro (Retina, 15-inch, Mid 2014)
Mac OS Sierra 10.12.3 (16D32)
