VST spikes causing audio drop and freeze during mixdown


While working on a project in Cubase 8.5 with VTS plug-ins from PowerCore Compact (http://www.tcelectronic.com/powercore-compact/) connected to PC via Digitus DS-30201-3 PCI-E fire wire card every approximately 3 minutes audio stops, and Cubase starts to behave strangely (permanent spike on VST monitor occurs). I have to restart Cubase to work on a project… for another passionate 3 minutes.

There is also problem when VST plug-ins are attached to project during mixdown to mp3. Progress freezes at random percentage and i have to kill Cubase in Windows task manager.

I’m desperate to find solution. I’m unable to work so far…
