Confusion by MSP Tutorial

I’m a bit confused by one of the examples shown and wonder if anyone can
offer some explanation.
The tutorial I refer to is MSP tutorials # 7 Additive Synthesis,
specifically the subpatcher “partial~” on page 99.
Supposedly this replaces an earlier patch that was comprised of 6 cosine
waves.
My confusion though is what is shown actually the replacement for all 6 ?
And , could I send say 6 different frequencies for the partials all at the
same time ?

TIA

I’m not completely sure of what you’re talking about, but there are
six oscillators and they are each playing partials of the main
frequency (the one box labeled frequency). If you make each one a
whole number, you will get harmonic overtones of that frequency,
thereby creating a new tone. If you use floats, you can possibly get
inharmonic overtones, also creating new tones. So you are really
controlling six different frequencies that are hopefully combining to
one sound.

You could, using the different control methods in max, control all the
partials at the same time. Let me know if I just wasted your time.

Also further down the tutorial went back to the partial~ subpatch so I was
able to understand better how it was used.
