Real Time Chord display

[Joel Pierson]

Playing a D Major 7 chord (D F# A C# )  the display is correct.  Lowering the 3rd & 7th indicates a D minor 7 which is correct. When I lower the 5th and the 7th again, it indicates a D dim 7 chord.  As far as I know, this is a fully diminished chord.  When I raise the 7th from there, I expect to see a half diminished chord but I don’t. EzKeys shows it as a Fm6 chord. Why?

The diminished 7th chord is made by having a root note, and having the rest of the notes with minor intervals. E.g., a C dim7 will be C–E♭–G♭–B♭♭

When you raise the 7th from that, it can also be written as a minor based on the second note in that interval (D# in the case of C dim7). In lots of cases, played keys can be described as many different chords, and we have made choices to only write one…

Henrik…thanks for taking time to reply.  I see D dim7 and Fm6 have the same notes.  The Fm6 is the first  inversion of D dim7.  You wrote “and we have made choices to only write one”  You don’t need to answer this but, the question in my mind is why ToonTrack choose that one?

Considering D dim and D half dim are controlled by the 7th, it seems to me calling the raised seventh version of the chord half diminished makes more sense than calling it Fm6 because the two diminished chords are related and easy to think about rather than the mental gymnastics involved in thinking a minor 3rd up from the root, adding a 6th and remembering it is the first inversion.

Good enough. We have a difference of opinion I can live with. At least when I run into this again, I’ll know what’s happening.

Thanks for your point of view! I don’t say that we’ve got it right on all algorithms. I’ll take your considerations into account for future updates/products!
