Dimetrios, This is indeed strange. Have you tried just using voice 1 and voice 2 in the B staff, since they will also be separate. Perhaps Sibelius is expecting there to be a voice 1, voice 2 in a staff before you can use voice 3 and voice 4?

I press the Alt+4 to move to Basso voice. But if I press the letter N, and i start to write the first note for Basso voice, Sibelius change the notes of tennore voice, becaus the color of Basso voice and the rests, are not enable. So, I can not find, How I can to activate the color of basso voice. An other example: I write the soprano and Alto voices, and after I move to piano B. I press the letter N, and the shortcut Alt+4. After I write the Basso voice. But if I move to the first bar, and I press Alt+3 to move to the tennore voice, if I start to write notes for tennore, Sibelius change the Basso voice now. So, the problem is on the piano B staff. Best regards, Dimitrios Tsakiridis.
