Modifying Note Names to identify notes in different octaves

• Jan 25, 2021 - 06:10

Hi all

I've been trying to modify the Notes Names plugin so that I can assign numbers to notes, however for this instrument in question, I'd like to identify notes that are an octave apart. So for example, a low C might have the number 1 assigned to it, but a higher C might have a 1* assigned to it. I've modified the plugin so that it's numbered but the A is assigned the same number regardless of where it is on the staff. Does each note have an id by any chance, that would help me achieve this?

Thanks

Each note has a pitch, divide it by 12 to get the octave.

This is how I do (I skipped some part of that function related to getting note head, accidentals, ...).
I put that in a note sub object (that I call extname, up-to-you to exploit that as you want)

function enrichNote(note) {
    // accidental
    //  ... skipped...

    // note name and octave
    var tpc={'tpc' : 0, 'name' : '?', 'raw' : '?'};
    var pitch=note.pitch;
    var pitchnote=pitchnotes[pitch % 12];
    var noteOctave=Math.floor(pitch/12)-1;

    for (var i = 0; i &lt; tpcs.length; i++) {
        var t = tpcs[i];
        if (note.tpc==t.tpc) {
            tpc=t;
            break;
        }
    }           

    if (pitchnote == "B" &amp;&amp; tpc.raw == "C") {
        noteOctave++;
    } else if (pitchnote == "C" &amp;&amp; tpc.raw == "B") {
        noteOctave--;
    }

    note.extname={"fullname": tpc.name+noteOctave, "name": tpc.raw+noteOctave, "raw": tpc.raw, "octave": noteOctave};

    // head
    //  ... skipped...

    return note;

}

readonly property var pitchnotes : [ 'C', 'C', 'D', 'D', 'E', 'F', 'F', 'G', 'G', 'A', 'A', 'B']
