Good morning, When I insert through in real time the notes of the right hand in a double line for piano.He erases my left hand notes. I think it’s a split problem, but I don’t know how to solve it. Do you have any suggestions?

Two suggestions: either engage chord input (shortcut Q) before you start recording, which will merge what you play into the music that’s already there; or show the caret on the staff into which you want to record before you start recording.

Perfect, thank you very much!
