I imported midi notes and data from Logic, and then selected transpose, as I am writing for horn. Dorico now shows me key signature as in G major/E minor. I would like to write everything without key signature, and I have tried to change the key signature in the tonality panel, but it seems to have no effect. How can I change this?
Select a “no key” Horn in the Player’s panel.
Yes, use Change Instrument to change your horn to one that doesn’t show a key signature:
