Hi Everyone.
I've run into this a couple of times as well. I haven't seen it happen lately but the difference is the projects I'm mixing right now do not have soft synths in them. When I was working with projects that included soft synths I had broken meters a couple of times. If I remember correctly restarting Sonar fixed it.
For those that have been dealing with broken meters do your projects have active soft synths or frozen synths in them?
