Hi Peter, thanks for your help. Now I´ve a single output object for output 6. But this object is controlled by output 5-6. The problem I detected now is that I´m not able to route a mono audio track per example on output 6. Turning the panorama knob from the mono track to the middle, I get a signal on output 5 and output 6. Turning it to left the signal appears only on output 5, but astable. The signal is only 10 sec loud then it gets quit though the levelmeter works. The same happens when turning the panorama knob to the right on output 6. I´m not able to route a monosignal outside Logic in mono. Whats wrong? wils > You have to make new audio-objects in the environment. So open > environment-window.
