Glissandos Change Notes when moved between staves
I am experiencing problems when writing glissandos for the Harp. I would like these glissandos to be diatonic, and span between the two staves. However, when I move the second note to the opposite stave (see images) [command/control + shift + up/down-arrow], the actual notes of the duration of the gliss in playback change, even though diatonic is still selected. Can anyone help me?
