The problem is with stem direction on middle-line notes. Finale gives them all down-stems. The rules of music notation are that the stem direction for these middle-line notes is determined by the stem direction of the surrounding notes. In large ensemble and long scores, it is very tedious and labor intensive to check, and correct as necessary, every middle-line note in the score.
It seems a relatively simple algorithm might address this.
I’ve been using Finale for over 30 years, and this problem has not yet been remedied.
