I have generated a chord sequence to practice sight-reading and I want to produce it in all keys. My problem is that I have always thought of the key between C and D as C#, yet when I load the C# sequence (from midi, which does not have key signatures) into MuseScore, MuseScore writes it as Db. I tried dropping the C# signature onto the score, which works beautifully for other keys, but when I do, it shows all sorts of naturals and flats. How can I get it to recognize and write the score as C#. (Actually, the same thing happens with F# and Gb.) I know I should learn Db and Gb, but I just want to see them as sharp keys, not flat.
