One of the most common criticism moved to Dorico is that new documents are not in 4/4 meter and in C Major. They are in an open meter and key.
In my view, this is one of the strongest points in Dorico, and one of the most innovative. I liked it immensely in Igor Engraver, and am immensely happy to find it again.
From the point of view of a student or beginner, having a blank staff is highly educative, since it forces one to learn how to choose the right meter and key. It is not a given, it has to be carefully considered. Having it ready is easier? It depends on the target. If someone only needs a way to transcribe a simple tune, maybe a program as complex as Dorico Pro is not the right one.
For someone writing music in the ‘academic’ styles since the 20th century (including much film music), having a blank staff is liberating. The idea of ‘flow’ is at the basis of Dorico, and flow is not only the name of one of the structural elements: it’s the deep philosophy of this program. Music flows. You are free to give it a measure, design patterns. But, at the basis, it is a free flow in time.
