Hi there
Im using Cubase Pro 11.0.30 i have recently installed SubLab 1.1.5 my issue is that it gives off crackle sounds no matter i change my buffer settings and reduce the number of vst instruments i use. i still hear the sound and when i close my DAW it does’nt close until i close it using Task Manager.

Yes, this shouldn’t be happening.

Let me check into it and get back.

Thanks,
Gavin.
