How to get there
Click the MIDI Tool . Select a region of measures. Specify the MIDI data type you want to edit by choosing Key Velocities from the MIDI Tool Menu. If you’re in the MIDI Tool window, select the region you want to affect by dragging through the "graph" display area or by selecting the handles of individual notes whose MIDI data you want to edit. Choose Randomize from the MIDI Tool Menu.
What it does
In this dialog box, you can direct Finale to alter the velocity for all selected notes at random. This can be a useful option if you want to give your playback a more imperfect, "human" feeling. (The Randomize command isn’t available if you’ve selected Continuous Data from the MIDI Tool Menu.)
Tip: Enter values between 5-20 to achieve a more "human" feel.
