How could I write "div." and "unis." in the score?
Sometimes when I need to divide the violin 1 into 2 parts and make them play different parts of chord, or divide into the solo part and ensemble part for temprory, how could I make it possible on the score and most importantly, how could I make them united again?
Also, if someone could tell me how to hide the instruments that don't have any notes to be played on the score, I would be appreciate!
