What is the correct procedure for adding a new measure in the middle of existing music, and giving that measure a new time signature?
When I add a new measure (using system track) and change the time signature, the correct time signature is attached to the measure but the duration of the measure is that of the previous measure.
Make sure Insert mode is on when changing the time signature, otherwise Dorico won’t add extra beats before an existing time signature. With Insert mode on, Dorico will increase the duration of the bar.
I’d recommend re-inputting the prevailing time signature at the start of the next bar first, if you haven’t already - otherwise the barlines will move according to the new time signature you input and that can be disorientating!
Thanks for your help! That works.
