Topic: Reduced quality stems after Virtualdj crash on Macbook Pro M1 Max
Hello! I have noticed that after Virtualdj had crashed due to loading of some problematic file (I have another topic post about these crashes) when it restarts I got a pop-up advising me that I should use reduced quality stems or pre-prepare them. When this happened I could see on the skin that stems were calculated at 1.3x speed. After I have restarted Virtualdj the stems were computed at 23x speed.
I'm using Virtualdj since 2005 and I love this software but now I'm in a quite desperate situation because of these crashes. Every time I load a file that's related to cloud drive or local cache I pray that Virtualdj won't crash but that's the subject of another topic. Now, I'm hoping that after crash the stems will work as expected (stems 2.0)

Laptop specs and performance settings:
Macbook Pro 16" M1 Max 64GB RAM 4TB SSD, 10 cores (8 performance and 2 efficiency), 32 graphic cores
