I’ve encountered a possible bug, but it may be that I simply don’t know how to make Dorico do what I want.
I have a flow written in 7/4 time. I entered [4+3]/4,1 in the time signature popover to obtain my desired time signature.
I have manually added (using Shift+B, then colon) dashed bar lines that bisect each bar in the appropriate spot.
The problem is, there are no measure numbers showing at the beginning of each system. Is there a way to force measure numbers to appear if they don’t by default?
