  3. Stuttering playback when VE is in background

  • Stuttering playback when VE is in background

    I have started encountering a weird issue. I moved most of my VSL samples (all except Dimension Strings) to an SSD which I have placed in an usb 3.0 enclosure. 

    The issue is that when I am working in Cubase, the playback starts to stutter and cut off. But the strange thing is that when I open up the VE window it goes away. As long as I keep the VE window up I don't experience these stutters.

    I have tried changing the preload to a low and a high number and it doesn't really affect this. It also doesn't matter if I have few or many instruments.

    I have never experienced this before so I am starting to think it's because of the USB SSD. Any idea what's causing this? It is strange though that everything works perfectly as long as the VE window is in view.

    Best Regards,

    Jörgen

    Edit: This also happens in Logic.

    Hi, I'm having the same issue. In addition to what you've said, I might add the next things:

    1. I had Chrome opened, closed it and it kept happening.

    2. Some of the logs state high CPU usage, althoug that is not quite what I seen on the meter (both on Logic and Activity Monitor)

    These are some of the logs:
