Scott,

I am not as musically educated as you are and didn't know these type of chords, but I was curious as to how my Technics KN6000 would recognize them. In fact the result was the same as you wrote, the only exeption is E1 - Bb1 - D2, that is recognized as C79 instead of C9:

F1 - C2 - E2: Dm9
F1 - B1 - E2: G13
E1 - A1 - D2: C69
F1 - G1 - Bb1 - D2: Gm7
E1 - Bb1 - D2: C79
E1 - F1 - A1- C2: FMaj7

I guess Technics did a good job when they developed the KN6000 back in 1999.
