Closing VST Instrument from Arturia crashes Cubase


When an instrument window from Arturia is closed, Cubase is crashing and closes itself. This happens since the last maintenance update 9.5.50


  • install an instrument from Arturia as VST-plugin
  • take Cubase Pro version 9.5.50
  • windows 10 os patches until KB4482887 (last kumulative update 2019-02)

Steps to reproduce

  • create a new project
  • create a new instrument track
  • choose a synth instrument from Arturia → The instrument is opened
  • close the instrument window → CPU usage raises → Cubase shuts down

Hi and welcome,

Could you attach a crash dump file located in Documents/Steinberg/Crash Dumps folder,r please?

I’ve got 9.5.50, and Arturia V collection (version 5) on Win10.

No problems with their stuff other than it takes quite a bit longer to load compared to other vsti’s.

Hi, I had the same issue with Fab Filter plugins, likely to be your GPU settings.
