Inputting key signatures with the panel
You can input key signatures using the Key Signatures, Tonality Systems, and Accidentals panel, both during step input and by adding them to existing music. You can also input key signatures only on single staves.
These steps describe inputting with the default mouse input preference Create item at selection.
Procedure
Result
During step input, key signatures are input at the caret position, even if this is in the middle of a bar. However, it is preferable to input key signature changes at barlines.
All subsequently input notes follow the input key signature, until the next existing key signature or the end of the flow, whichever comes first. If playing in notes using a MIDI keyboard, accidentals are spelled according to the key signature.
When adding key signatures to existing music, they are added immediately to the right of a barline, or immediately to the left of a selected note, even if this is in the middle of an existing bar. If you selected an existing key signature, the new key signature directly replaces the existing one.
An individual key signature on a single staff is not intended for transposing instruments. Transpositions of notes and key signatures are done automatically for transposing instruments.
