MasterPage provides a unified control panel for GrandMA3 masters in a single overlay. Instead of hunting through menus or using up valuable faders to adjust Groupmasters or other master types; This plugin displays 12 customizable fader controls on top of the programmer letterbox screen. Assign any master or group to each fader, then control everything from one consolidated interface that stays out of the way and keeps your other screens clear.
