Mel is correct.

Note that BIAB does not support entering a chord type of "add9" so you have to use "2". For example, to get Fadd9, type F2.

Explanation: you can always subtract the number 7 from a scale tone that is higher than an octave and get the same pitch an octave lower, so 9 - 7 = 2. Both are the note G in the key of F major. You get the same pitches as an add9, just in a different inversion. Styles take care of the voicing automatically.

To see possible chord types allowed in BIAB, right-click and select Chord Builder. Many are listed in the 'Other' dropdown list.
