I discussed Dorico’s handling of ottava clefs with Daniel in the early days, though there seems to be some new functionality, which might be helpful, if I could get it to work.
In Dorico, ottava clefs don’t transpose the octave by default. So changing from a Treble G clef to a Tenor G clef does not affect the notes’ position or playback. Transposition is done to the instrument, so a Tenor voice Player is down an octave, no matter what clef is used.
However, the Edit menu > Clef submenu has “Concert Pitch” and “Transposed Pitch” options, each with a list of all the clefs. But I can’t work out how to use these for what I want. (Or rather, I can click on the menu items when I have stuff selected, but nothing happens.)
I’m transcribing some Renaissance music from a manuscript, which uses a variety of C clefs, and once I’ve typed all the music in, I’ll convert the lines to modern clefs. So I want to type in the vocal lines at pitch using C clefs, and then change to Tenor G clefs, or Treble G clefs, or even Bass clefs, as appropriate for the range, without having to worry about things being at the wrong octave.
