Same on my system. I play only one note and the voices run out ( red) and the sound break.
It seemed the drive (SSD) wakes up some time. But switching on release samples and velocity x fade it gets unusable.
For what a machine is this library made? Future rockets? You need 4 machines for violins,viola,celli and KB. And it still crackle.
I run 7 pc spread out all my librarys , but dimension still overload the voices.
Study the manual twice, just tryed the latest updates - no change
