I want to create a vertical line to indicate that two things are simultaneous, as in the attached screenshot from Sibelius.
(Why? This is sometimes necessary to indicate precise timing between metered rhythms and items whose timing is inherently imprecise, usually because the timing is indicated by position, e.g. grace notes, pedalings, dynamics, and spatial notation. It is also helpful for mutual cueing between chamber players who are reading off the score. The attached screenshot is an example of both: the dotted lines show a free-rhythm singer and a metered piano where they should line up.)
The closest solution I’ve found is here: https://www.steinberg.net/forums/viewtopic.php?t=104732 I’ve experimented with this solution, and it poses a bunch of problems:
- There’s no way to make gliss lines dotted.
- It’s not possible to attach a gliss to two simultaneous, vertically aligned notes. That’s clearly correct for a gliss, but for this purpose, it forces me to give one endpoint a fake attachment to a neighboring note. This has two ill effects:
- It messes up the note spacing, because Dorico leaves room for the gliss even after I’ve adjusted the fake endpoint to make the line vertical.
- Because one endpoint is always attached the that neighboring note, the line does not stay vertical when note spacing changes.
- It’s impossible to attach the gliss to two notes on different staves, so one end keeps getting out of alignment as staff spacing changes.
I’m guessing that this is just beyond Dorico at the moment, but is there any better way to fake it?
