Glissando lines across empty bars
In Dorico, 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 shows notes or rests in every bar.
Once you have input a glissando line between the selected notes, you can hide/show any implicit rests between them.
If there are any explicit rests between the notes at each end of the glissando line, you must first turn them into implicit rests.
