Hi,
I would like to ask you about the possibility of the barlines.
How to make:
1: create an invisible barline - but only for one instrument…
2: creating different kind of barlines, for each instrument
grazie 
Yes this is pretty easy in Dorico, because Dorico allows you to input different time signatures on each staff (see here), and once you’ve got a staff-independent time signature, you can input barlines on those staves only as well (see here). If you want, you can also hide any time signatures you don’t want to show.
For your first example where you want invisible barlines, you could input an “open” time signature for that staff, meaning Dorico automatically doesn’t show barlines until you input one explicitly or change the time signature.
(Edit March 2021: updated links to 3.5 manual)
so beautiful / thx
Hello Lillie. I was searching for answers to a similar question and would like to check out your solution but the links seem to not work anymore. It would be great to check them out if it would be possible to fix them.
Thank you very much!
Hello, Yes those links were from before we did some restructuring and of course pointed to the v3 manual, which is no longer the most recent version. I’ve updated the links now to 3.5 and they should all work.
