I am importing an XML file into Dorico, and the notes all come into a single treble clef stave. This is okay, but I would like to split this music across a piano roll (notes at and above middle C onto the treble clef, notes below middle C onto the bass clef).
My guess is to select all those notes destined for the bass clef, then (assuming you have an empty bass clef ready), select alt/option M to move them to the clef below.
RobF offers the easiest way I can figure out how to do it. It is very, very time consuming. We really need a ārenotateā function like a certain other notation program offers.
I have had some luck with exporting the offending passage as midi then importing it back in. It usually splits okay.
