In a major key, diatonic harmony, the dimished triad occurs as chord VII. While it's use is limited, it is nonetheless sometimes useful when a softer, gentler dominant sound is required.

In a minor key, diatonic harmony, the dimished triad occurs more than once. It's biggest use, though, is chord II where it has exactly the same function as chord II in major. For example, writing a song in C minor without having Dmb5 available is the same as writing a song in C major without having Dm available.

Is it possible to add this triad to the myriad of chord types that BIAB supports?
