I’m trying to change my Key Signature (at bar 17 of a piece). I select the first note of the bar, do Shift-K, fill in the pop-up box with the new key signature - and then nothing. Nothing that I can see changes in my score. I don’t see the new signature, nor do the currently displayed accidentals change.
Could someone tell me what I’m missing here? Thanks.
When you say “fill in the pop-up box”, what exactly are you typing? The syntax is upper-case letter for major, or lower-case for minor, e.g. d for D minor or E for E major.
Is this by any chance a part for a “No key sig” instrument? In that case you would see a double bar at the end of the previous measure, and any other instruments in the score would actually receive the key signature.
edit: Yes it is. In Setup mode, choose “Change Instrument” and from the list of trumpets, choose “C” instead of “C No key sig”.
Yes, that is a convention for horns and trumpets in classical scores due to their history as valveless instruments, restricted to a particular overtone series. See here for a detailed explanation.
