How to combine note durations?
I copied a midi arrangement and pasted it into MuseScore. It worked surprisingly well. It took some cleaning up, because of funny time signatures and several changes of time signature. It's all good now, except there are many places where several quarter notes, all the same pitch, are tied together. How to I change four tied quarter notes of the same note into a whole note, or three tied quarter notes into a dotted half note, and so on?
