I updated Cubase to the latest version this afternoon hoping for a smooth transition. At first things seemed OK then suddenly my computer screen went black and it rebooted in the middle my work flow. After my computer rebooted I fired up Cubase and continued my work. Ten minutes later the screen went black and the computer refused to reboot.
I put it up on the bench, swapped out the power supply and graphics card to no avail. Eventually I was able to get my computer to reboot using the same hardware configuration it had before I installed Cubase 9.0.20. I restarted Cubase to continue my work and five minutes later it went black and rebooted a third time.
Out of desperation I uninstalled Cubase, reinstalled it only applying the 9.0.10 update and everything seems fine again. All the plugins I use are fairly recent 64-bit Native Instruments or Steinberg FX & VSTis. I do use SpinAudio Roomverb which is 32-bit plugin connected via J Bridge. I’m not sure if this caused the crash in 9.0.20 but it’s never been an issue in 9.0 or 9.0.10
I will try Cubase 9.0.20 again without any J Bridged plugins and see if that makes any difference. That test will have to wait a few weeks as I’m in the middle of a project and don’t have time to spare for harware or software testing.
