"Harmony analysis tool" plugin does not take into account transposing instruments

Thanks for info! Since I'm focused on piano music, I never noticed this problem.
I'm quite low on free time these days so I can not promise anything but I'll try to see can I do something about it.
Anyway, I'm glad to hear that someone is using the tool :)

Hi again.
Actually, it was trivial to solve this issue.
I updated the plugin code so you can download it now and try.

I'll explain the solution here for someone interested in writing plugins. When working with note element, you can get its pitch class by using three different properties: tpc1 which always gives concert pitch, tpc2 which always gives transposing pitch and tpc which gives either concert or transposing pitch (as per current "Concert Pitch" setting). Thus, the solution was to simply use tpc1 property instead of tpc property.

    var selection = curScore.selection;
    var elements = selection.elements;
    for (var i = 0; i < elements.length; i++) {
        var element = elements[i]
        if (element.type == Element.NOTE) {
            selectedTpc[element.tpc1 + 1] = true;
            if (element.pitch < minPitch) { 
                minPitch = element.pitch;
                minPitchTpc = element.tpc1; 
            }
        }
    }
