No Time Signature

I am starting to write some choral music in the coming year. Some of this music is Chant choral music without time signatures. How do I get rid of time signatures in Dorico 2? Thanks

If you don’t want time signatures for part of a flow, press M for the time signature (measure) popover, then type “open” (without the quotes).

When you start a flow, there is no default time signature anyway (unlike most other notation software), so don’t create one if you don’t want it - just start entering notes.

Chant transcriptions are a breeze in Dorico. Don’t forget about the “hide stem” property in engrave mode. You can select all, filter to notes only, and then hide all the stems with one click.
