In Dorico Pro, you can input glissando lines between any two notes, even if there are rests or other notes between them, and including between notes in different voices and notes on different staves.
For very long glissando lines that extend across multiple bars, you might not want to show pitches at the start of each bar; for example, to indicate that performers do not emphasize pitches during the course of the glissando, or that performers can play the glissando at their own speed. By default, Dorico Pro shows notes or rests in every bar.
To avoid note spacing issues caused by removing rests, we recommend inputting notes in the intervening bars, then hiding their noteheads and/or stems.
