Mainstage is not recognizing proper MIDI keyboard keys?
I have plugged an M-Audio Keystation 61es into my Macbook pro. Mainstage (and Garageband) recognize the keyboard but all the notes are a semi tone up. For example, when I hit the C1 key on the Keyboard, the software recognizes and plays C#1. Any solutions?
