I'm struggling to fully understand this tbh, but was recently exposed to these subtle differences when writing a mini organ synth. When implementing the draw bars (dictating the harmonics comprising each key) I realised the true harmonics of a note and neighbouring notes calculated in the 2^n/12 way are sometimes the same and sometimes slightly off... organs just kinda ignore this fact and use the closest neighbouring notes for the draw bars anyway so that they don't need a million different oscillators, so technically the draw bars are just chords on the keyboard using the same oscillators and not harmonics (well some of them happen to be exactly the same as harmonics, others not).
