Remember, if you are using X series SONAR to post in the forum above this one. Creating a master bus is easy. Create a bus, name it Master, right-click on the buss and select "Set as Default Bus", set the output to the main stereo out of your audio interface. Done. Now any new tracks or busses will point the the Master. Existing tracks and busses will have to manually adjusted. You could also setup a template for this. The normal.cwt is already setup this way by default.
