MainStage Change the tuning for a concert
By default, concerts use equal tempered tuning. You can change the tuning for a concert so that it uses a different tuning.
Change the concert tuning
In the Concert settings, click the Tuning tab.
Choose the tuning you want the concert to use from the Method pop-up menu.
When you change the tuning of a concert, the tuning of the patches and sets in the concert changes if their Tuning Method is set to “Use parent tuning.” Patches and sets with a different tuning method are not affected.
