I finished a vocal arrangement. In the last chorus there is a section written as unison. The artist wanted it changed to parts. The song is in 3/4, the first bar to change is a D chord and the note written on the treble clef is a dotted half note A above middle C. Needed to change this to an F# over D above Middle C. So I entered the D and the F# easily enough but could not delete the A. I tried everything listed in the manual, all the suggestions listed in the forums with no luck. I finally ended up deleting each measure and entering the notes, and then had to go back and re-enter the lyrics and the chord names. I'm working on a Macbook pro. I know there must be a simple solution to this, there always is, but I haven't been able to find it.
