Bob,
I'm a guitar AND keyboard player, not that great at either except at chords and harmony. So I know many voicings for pretty much all chords--yes, on guitar you have to compromise a bit but you will still get a rich sounding chord using guitar voicings that have been worked out by all the great players and teachers of the past.

And it's the same with keyboard except there are many more options for voicings. However, great keyboard players generally DON'T put every chord factor into voicings and very often omit tones that muddy up the sound (like 5ths and even 3rds in some cases).

I'm just getting re-started with BIAB after years of neglect, so I'm sticking with pure MIDI right now until I get up to speed with the program.

What I need to know is how to edit BIAB chord voicings in editable notation into ones that I want, then making them stick into the arrangement.
