No sound in Cubase on tracks with volume automation

Yesterday I got the same problem. I placed volume automation to one track and cutoff automation to another in my project. And I have next symptoms now:

  • if song plays repeatedly, I lost all sound in all track in period from 10 to 40 minutes while I start to play song
  • if I making something changes in VST inserts (EQ’s, Compressors or any), Cubase lost sound immediately or for 30 seconds later for all tracks in song, when I close plugin window.
  • If I changing synth parameters on track where volume automation presents, Cubase lost sound for all tracks immediately.

This is really nightmare to me. I restart cubase 50 times for the last hour.
