this is a bug in Human Playback since a long time, but still present on new Finale releases:
When only some staves are selected, through View->Program(Select) staff set, Human Playback fails to play dynamics and legato/articulations, giving to playback unpredictable results, with also an unbalanced mixing.
Everything is back to normal when all the staves in the score are displayed (through "All Staves" item, on the same menu).
Could be possible to fix this bug in the upcoming 27.3 update?
This would help A LOT people who are working with smaller screens or, for whatever reason, who needs to work only on partial number of staves using this very useful option (Program / Select staff set) in View menu in Finale.
