There was something I noticed.
When I start Sonar and I open a project and (with luck!)
the master fader works, every project that I will open without closing Sonar the master fader will work too.
If I open Sonar and a project and (bad luck!) the master fader does not work all the project that I will open without closing Sonar master fader will not work.
I do not know if it may mean something.
thanks
