You can enter notes of any rhythmic value (quarter note, eighth note, and so on) into the score with or without MIDI keyboard input. You can also change any existing note’s value (or region of notes) without having to re-enter them.
For instructions on adding and deleting notes, see Simple Entry and Speedy Entry.
To change the note values in a selected region
If you want Finale to re-bar the selected measures so that the proper number of beats appears in each measure, make sure Rebar Measures is selected. See Change Note Durations dialog box for details on these options.
Finally, note that this command does not affect empty measures. (A measure in which you’ve entered a “real” whole rest doesn’t count as empty in this context.) That is, it will double the values of all notes and rests you’ve entered, but it won’t create a second completely empty measure.
