Fabio, this looks like hide the hands.... if Cubase 6.5 does not have these problems with all 3rd parts plugs, why Cubase 7 have it? I don't speak about the mixer horrible concept they gave us.... unusable, unreadable.
So we have to test all these plugs for Steinberg?
Nope, sorry. It is the 3rd party developers that need to test their software with Cubase, not the other way around.
We also do not have licenses or know all of the stuff out there. I'm gladly testing the ones I privately own licenses for and download demos of the problematic ones when I receive a report. But it is the plug-in which needs to be tested in Cubase, not the other way around. A host cannot be built around plug-ins.
