As you can see from this image there is a random bar with 5 beats in it. Everything is in 4/4 time as evidenced by the other bars around it. I admit to really struggling with this software but I just can’t figure out how to make Dorico remove the extra beat.
Please show the signposts (menu View > Signposts > Show Signposts). Probably there are hidden time signature changes.
If so delete the 5/4 signpost, which results in a 4/4 and an 1/4 bar, delete the 1/4 bar with SHIFT B-1 and delete also the obsolete remaining 4/4 signpost.
The “Signpost” says “4/4 (q, 1+1+1+1)”. What does that even mean, and more importantly, how does that suggest that it is appropriate to put 5 beats into every bar of 4/4 time? I just don’t get it.
I don’t even know what that is. I’m trying to transition into Dorico from decades in other composing software and everything is just so counterintuitive to me. ¯\(ツ)/¯
I’ve had this problem before with files I imported from Finale. It’s usually due to Finale’s Independent Time Signature feature being activated for that bar.
If you double click the time signature you will likely see 4/4,5 in the popover. That means a 4/4 time signature with 5 beats in the bar (which Dorico will treat it as a pickup bar, so the following bars will all be straight 4-beats)
I know you are frustrated with Dorico - but it is essential you get your head around how Dorico handles “musical time”.
It is a good idea to do a lot of experimentation (eg. take some simple scales and add a new time signature at then end. Then add some intermediate time signatures and see what happens - with and without the various insert modes being turned on)
I’d insert two measures at the 3rd measure in the image (select the whole note, press Shift-B and then +2). After that, you can transfer the contents of measures 5 and 6 (3 and 4 in the image) to the new measures (make sure you deselect the time signature change). Once you do so, you can delete measures 5 and 6 (click the bar above the measure). If the time signature change remains, you can just delete it.
You can also delete the corrupted measure in the original file and then re-insert it in Dorico manually (not copy-paste). If you do this, be sure to save extra copies as necessary.
I sometimes get this problem, so I create a new bar next to it, copy and paste the original notation into the new bar and delete the offending bar. Works for me.
