Plugin for labeling harmonic changes

I wonder if there is a working plugin to add labels based on what is happening in the audio analyzing the harmonics of a song?

I can use label sounds but it is restricted to amplitude. I need regular interval labels (which I use now) but I would like every label to be put on a hamonic change or another clearly noticable change in the music. The audio files I need to apply this to is always music.

I found some plugins that might do what I am looking for but it seems that they are to old or just made for windows 32bit.

Found this page that seems to contain what I am looking for

Plugins that I tried but couldn’t install,mapped%20to%20a%20single%20octave.
