Hi! Since the days of Sonar X1, I sometimes had problems with phase (anti-phase). I had tried to solve it by all means, which I could find, but, to date it keeps popping up from time to time. It doesn't happen often, but when it does, there is no way to remove the annoying "flanger" sound. I've figured out a way to fix it - disable/enable all sends to buss on any track, but after saving the project, when I open it again, the problem remains.
Can anyone suggest any ideas, what this phenomenon depends on and how can I avoid it?
