Piano reduction voices problem

Hello,

I have made a piano reduction for a vocal quartet and noticed that in some places (only for Soprano and Alto) the voices are not nicely done. I wonder if there are any tricks to prevent the manual intervention.
Thank you.

There’s no automatic way to produce a piano reduction that will use a single voice when the rhythms align but not at other times: you can select music and merge the music together using the commands in the Edit > Voice menu.
