Dorico Transpose Horn Issue

Dorico
1

I am using the latest version of Dorico. To write the Horn part for Beethoven’s Piano Concerto No. 2 in Bb major, I hovered over the instrument and pressed Shift+K. Then, I typed ‘B’ and used Alt+Enter to transpose the Horn instrument to B. As you can see in the example, when I enter the first note, it plays a B natural sound. However, for all other instruments, the first note is Bb. Did Beethoven prefer it this way, or am I making a mistake somewhere? Please help. By the way, I don’t speak English; I used Chat GPT for the translation. I hope you understand my issue

I think you have a few things confused here. First “in B” refers to the Horn transposition, not the key signature, and second “B” in German is really “Bb.” (“H” is B natural.) So this is a Horn in Bb part. Just use Edit/Transposed Pitch if you want to input transposed.

B in German (original score) is Bb in English. So you entered a half step too high.
