There used to be a Band In A Box auto-harmonize plugin but I think that's long gone. I remember trying it in Finale 1998. I don't know what might have taken its place—if anything.

Yeah Mike,  I thought I'd find a magic bullet with the layers also by trying to copy the 1st layer and then add a new layer and paste the note in and re position the new voices up..   Good thing i saved my work first!

Layers are the ticket if you want to have two or more parts with different time values,  1/4 notes over a whole note.. etc.

I was hoping for an easy way to literally stack notes of the same duration in a chord.  All the same value..    Example    CEG,  CFA.  Etc.

I'm sure there must be a trick to it.  finale's been around way too long for something that seems like it should be so simple.  In the time it takes me to figure out what they possibly call it, and find it, I'll be done.

T thought I'd put it out here since I will probably be doing a lot of this type of thing in the near future.

Thanks for the input.

Investing in a MIDI keyboard might not be a bad idea.

Any chance that you are not in Finale 25? The Band In a Box plugin is still in 2014.5 — I just checked. It does exactly what you want. Here's a tutorial from 2010:

If there's a modern plugin that takes its place in 25, I don't know. I can't find it in the new, useless online Help nor in the 25 plugins menu.

There are many plugins for DAWs that can do this but I don't know how you would use them with Finale. 25. You still can do it in BIAB and export as MIDI or MusicXML back to Finale.

The ability to stack notes on top of notes to easily create chords has been present in both PC and Mac versions of Finale for quite some time.

If you know the chord voicing you want to display it can easily be done using the Simple Entry Tool and the computer keyboard number keys located on the top row of the keyboard (not the numeric keypad). Here's how it works.

To enter a root position G major chord  -

1. Using the Simple Entry Tool, select a rhythm and enter a "G" note on the second line of the treble staff. This will be the lowest note of the chord.

2.  To enter the next note, "B", select the 3# key on the top row of the keyboard - the "B" note (a 3rd above "G") should be added using the same rhythm.

3. Use the exact same procedure to enter the next note, "D"; a 3rd above the "B" .

4. The final note "G", is a fourth above the "D". This time select the 4$ key to add the "G".

To recap, a G major chord may be entered by placing a "G" note on the staff followed by the numbers 3, 3, 4, which will result in the addition of the  "B", "D", and "G" notes above the starting "G". The notes are placed based on their intervalic relationship to the highest note displayed.
