Thanks Abraham I have read that section again and I am still a bit confused at what I am seeing in this attempt at a MWE. In bar 2 the voiceTwo notes are shifted right, but in bar 5 the voiceOne note, a dotted note, is being shifted to the right. I have tried using the Staff.NoteCollision.prefer-dotted-right override but that doesn’t seem to help. In bar 7 there is a different construct with temporary voices and there the shifting looks like what I want. I am trying to get the dotted stemUp note in bar 5 to be shifted left.
