Unfortunately, those additional global settings did not allow to enter custom midi commands like Action 1 & 2 do. My workaround is to run both ST3 and OnSong side-by-side. At this point, I am primarily using OsSong and a midi footpedal progammer to control actions outside ST3, like the Behringer XR-18 and the Beat Buddy. I will run all my lyrics and tracks from ST3.
Peter, maybe you can add several more Action options to version 4. The more the better.
