I have confirmed with the techs that Finale cannot flow notes that no longer fit in a bar after you've changed the meter.
For example, imagine 2 bars of music in 4/4.
Change bar 1 to 5/4.
A quarter rest is added by Finale! (Finale is not a composer, and should not be changing what notes come next!)
What was formerly on beat 1 of bar 2 should now be on beat 4 of bar 1.
Finale should flow the music from the right to the left to keep the music sounding the same.
Finale recognizes that notes should be shifted when meters are changed, but can only do so in the opposite situation: "Rebar Music" can shift notes to the right in you were to change bar 1 to 3/4 instead of 5/4.
Speedy note entry can also shift to the right if you add an extra beat in a bar.
SHIFT TO THE LEFT!
