Dorico’s way of handling beam works wonderfully in 4/4. I almost never have to manually adjust beaming or use force duration. However, this is not the case in other time signatures. The following photo shows two lines of music: top one I have manually adjusted, and the bottom is Dorico’s default.
I feel that the beaming algorithm needs serious updating for these times signatures as a lot of the default beamings are not correct.
The rule I am following is that everything is beamed in quarter note groups. Adjacent pairs of quarter notes may be beamed together provided they don’t cross the half bar (such as in 4/4, 6/4) or a major pulse in a hybrid metre (5/4, 7/4)
I hope this is something that will be fixed to work as well as it does in 4/4.
