please please please ..... minor add9 without any other extensions: a simple minor triad with a 9th added. Standard pop and rock chords.

while I am at it, I'll write here some other notes that I took over the years and put them in my BB manual. As much as I love the program, I'd really like to see these little things sorted:

if you enter E5/ A , bb plays a G sharp. Why ? an E5 should just be a perfect fifth , adding the third defeats the whole thing

if you enter B dim /D , bb plays a B dim7 , a completely different chord. The B dim/ D is simply a diminished triad taken in first inversion, that's the way it's used in classical music because these guys say that if you play the B dim with the B in the bass, the chord will sound harsher than if you play the same triad with the D in the bass.

even if you tick off the 'allow embellishment of chord' option, BB often plays F sharp on a C maj7, or it will play the ninth anyways on an Abmaj7

all this stuff works well in jazz, but not so well in other genres
