How do I get rid of unwanted instrument numbers?
To explain: This is my first major project in Dorico 2. I have created the project by importing several MIDI files, which became separate flows. In importing the files Dorico has (arbitrarily, as far as I can see) assigned different instrument numbers to what I consider to be different instances of the same instrument. For example, there is only one marimba in the score, but in various flows, Dorico has labeled it “Marimba 1”, “Marimba 2”, “Marimba 3”, or “Marimba 4”. In no instance does more than one marimba occur in a given flow. Other instruments are labeled in a similar fashion. I want all instances of the marimba throughout the score to be simply labeled “Marimba”. How do I achieve this?
