It is very difficult to explain, therefore please try on your DAW - select program “Angie D” (“Brite One”, “Elenox”, “Hands Up!” and some others) and play one note repeatedly for some time. If the chord varies between minor and major, then you have the same situation what I cannot understand nor explain.
The question - is this normal? This is not on all programs. Only on those where chords stored. But if I load program named “Stoned Games MW” which compiled as chord, it plays normally in major on all notes for any count of repeated notes.
