Grand staff: Ottava on one staff shouldn't affect cross-staff notes displayed on other staff
The example shows two same passages with concert pitch and ottava notations. The ottava one will guide the player to play correctly as the concert pitch version, but Musescore lays the cross-staff notes an octave higher, and so does the braille transcription. As for braille transcription, We want a result with pitches in correct octave, so is there a way to detect and render cross-staff notes out of the ottava line without doing any fake things like hidden ottava lines for playback and visible line imitating ottava visually? Also, if there's an ottava line added on the other staff, Musescore should detect it and apply ottava correctly. I know the reason why Musescore plays incorrectly: the passage is in a single voice, and ottava line applies to the whole staff. I hope Musescore can exclude ottava from cross-staff notes, so that both sound and braille are correct, and Musescore will be the first notation software handling this correctly.
