I am new to Dorico and all software for composing music. I would like to use Dorico for writing and playing music, particularly for string quartet. The thing I am unsure about is how much control I can have over the sound produced. I tried Dorico 2 and I was frustrated that I could not even change the loudness of the instruments with e.g. ff or <. Do I need to buy something else as well as Dorico?
