Automatic Chord Identifier

I saw: https://musescore.org/en/project/chordidentifier
It is interesting for those who have to learn and I reported it here and on the other side of the pond. It follows a request: It would be possible to have a variation as highlighted in red:

Thanks to rousselmanu for the valuable work

Hi Shoichi,

I just published a new version (v1.1) which does what you want (example here ).

You can set the inversion notation you want by modifying parameters INVERSION_NOTATION and DISPLAY_BASS_NOTE (lines 66 and 70 ) in the plugin file.

Default is now INVERSION_NOTATION=1 (Figured bass of inversions) and DISPLAY_BASS_NOTE=1 (display bass note like C/E for first inversion C chord)

Enjoy ;-)

Many thanks! I am going to break the news and I imagine a further request ;-)
__edit__
only to report the raised objection I attach a picture (because I'm not a musician or computer expert). I will try to figure out how to modify the plugin (Not sure if I'll be able)
to obtain eg:
only Dm/A e D/F#
or Dm/A and D/F# with the bass numbers below the staff.
Thanks again for your time.

Good call! Yes, we write just Dm/A or D/F#, we do *not* write Dm64/A or D6/F#. We don't even write Dm64 or D6 - the "64" and "6" nomenclature are *only* for use with Roman numeral analysis, not for chord symbols. In the key of D, the chord symbol D/F# is F#-A-D and is analyzed as I6 in Roman numerals. The chord symbol D6, on the other hand, is D-F#-A-B - a D triad with an added sixth - and really doesn't have any particular standard representation in Roman numeral analysis.

I just modified the plugin to fix this notation issue. It doesn't show the bass numbers below the staff yet, probably in a future release ;-)
It also includes a major rewrite of the chord identification algorithm to make it more robust. And now chords are identified even if they include some Non Chord Tones (in the sense of classical music).
You can have a look at the attached picture (NCTs stay in black).
