ScoreCloud won't allow an accidental to be written on both notes of an octave - only on one. The other accidental can still be "invisibly" entered so that the note is correct during playback -- but it can't be written into the score that way. This would be incorrect musical grammar (at least in classical music where both notes of an octave require the accidental; I'm not sure about other forms of music). ScoreCloud has the same issue not only with accidentals that fall on octaves, but also with accidentals on two different pitches of the same note elsewhere in a measure (lets say an A4 on the first beat and an A5 on the 2nd beat - they'd both require an accidental, because even though they're both As, they're different pitches of A).
It would be so wonderful to be able to have this ability in ScoreCloud . . I've been writing out the missing accidentals by hand. Many thanks for your consideration!
