What are you trying to do differently than your old post from 2012, Creating (a single) harmonic?
Well at the former post (2012) I was trying to add a single harmonic, now I'm trying to add a batch of harmonics (say 6-8 or 10) at the same go.

Let me rephrase my post. What I'm really "investigating" here is exciters.
In this case I'm using Flowstone for trying out effects not instruments, meaning that input is music (uknown audio stream within the DAW) and output is audio stream, so I can't just replace a synthesized sine wave with a richer form, since nothing here is synthesized in the first place.
Think of an exciter effect like these:

So, I'm playing with taking an audio stream and processing it so that the output is "richer".
For starters, my input is sine wave and I expect the output to be controlled"
A. Original input (sine wave)
B. Even harmonics
C. Odd harmonics
A,B,C each having their own "intensity" knob for the user to mix and get interesting results.
Hope this is clearer
If so, let me return to the original question...
Is there a way to create odd harmonics without the fundamental being present at the output?
For a sine wave input (special case) the output should be x3,x5,x7 of the input, without x1...
As mentioned, for even harmonics it is doable, but for odd ??
