Harmonics into Semitones

[jmg8]

Thanks for everyone taking the time to try and explain this to me.
To be clear the reason I am asking is that, I am making my own harmonic OSC in MSF so I can experiment with per voice modulation for each harmonic individually. Here is a crude mock-up.

So to start with I am making this with 16 OSCs all set to sine. I needed to know at what pitch to set each OSC to make the harmonic series. In this scenario, I will not know the frequency, as I can not know what note someone will press when playing with the synth. So I needed a way to offset each OSC by semitones (and cents)
I believe Werzel came up with the correct solution for me here, thanks

So I will start to experiment with it and hopefully, it will work as expected.
My only worry is this: Will the difference in semitones change depending on which note I input, or will they always stay the same difference apart?

A question, how have you do the "macro" ?with multiparameter and edit page?- I refer to that:

It's look good!

I just did it in photoshop.

If you are looking to drive yourself completely crazy, you can change all of the + signs to - and - signs to + (including the semitones) to get the undertone series, where the undertones are below the fundamental tone.
When you write the harmonic series and the undertone series out musically, they are mirror images of one another.

WOW, 32. Thanks for taking the time to do that, much appreciated.
Also, I didn't know about undertones! I will look into that.

By advanced mode, you mean harmonic mode right?

Yes, Harmonic mode is exactly what I meant. Sorry about that. I use a computer other my DAW to access this forum and my memory can be faulty at times.

That will not work, as the level of each harmonic is not per voice modulatable. That is the reason I am trying to mimic the harmonic OSC using individual OSCs, so I get per voice control over each harmonic.

I neglected to mention that you'd need to add a utility module under the oscillator module to control the level and for the utility volume to be the target of modulation. Harmonic mode just governs the relative loudness of individual partials, so even if you could modulate the individual harmonic levels, it wouldn't work the way you wanted anyway.

In any case, it looks like you have a solution. I found it difficult to understand how the semitone offsets changed depending upon the fundamental note/pitch, but I didn't have time to investigate further. I'm glad this got sorted out.
