Kelso:

I don't think you'll find what you're after.
BIAB doesn't keep track of the "original" chords that were entered, if you entered them yourself,
so there's no way to set them back to a "default".

If BIAB created the chords in the first place, say from a MIDI file you loaded, then you could
simply start a new song with that MIDI file and have BIAB create them again.

Another option to explore is the Edit Menu's "Jazz Up" and "Jazz Down" the chords if that works in this case.
Possibly the best way would be (in hindsight of course <grin>), save the song before doing any mods with the
(say) Chord Options dialog, then make the changes and save with a new name.

The only other thing I can think of is, if you had the ACW generate the original chords from a wave file,
and then you changed them, you could start again with the original wave file.

Let us know if I've interpreted your problem incorrectly.
Someone wiser may be able to offer a better solution.

Good luck!
