Independant time signatures and independant tempos at the same bar
(Imagine an orchestra, where the flute plays at 80, the piano at 60 and the oboe at 75. Different places for each barline and each instrument... That's what I'm talking about)
So let's start with the simple stuff and move towards our goal (as descirbed in the above sentence

)
Example 4.1
Here things are completely normal. No problem whatsoever. Both instruments at 60 tempo, and at 4/4. Now, notice that the one has a dashed barline, and the other a normal one. Finale 2007 has a choice to not show the barlines of any staff you require. Just go to [i]staff tool ->staff attributes ->items to display (on the right) -> uncheck barlines[i]. Replace the barlines with the one, given to you on the
expression (mf) tool ->shapes.
For our goal,
always the Flute staff does not display the barlines. Ok?
Example 4.2
Goint once more to
staff tool ->staff attributes ->Independant elements and checking time signature, will enable you to change time signatures at each staff on their own! Pretty useful! But notice what happens? Automatically Finale (any version) will
allign the barlines and not the notes. Thus in this instance, in the example 4.2, quarter in the flute lasts longer than the quarter in the oboe.
It is exactly the following example, written more elaborately (but for no reason):
