Mainstage 3 Blank Keyboard Layout... Help!!
Hello, I've been using Mainstage 3 for over a year but today I opened the same concert I've been using and the screen control is blank. I can't find any of the Hammond B3, Electric Piano and Piano smart controls default window that came in the software. Please help me! I will attach a picture so you can see what I mean.. 😟
