Quickest way to find harmonics for manipulation (in PVS?)

SubjectQuickest way to find harmonics for manipulation (in PVS?)
Hey hey,
I'd like to find and manipulate harmonics. I assume PVS is the way to go, 
starting with a pitchtracking opcode. But what then? My idea:
use pvsftw pvsftr to go through the bins and find the relevant frequencies and 
then modify the related amplitudes or even slightly shift the frequencies.

Since bins are regularly spaced, I assume that I can optimise the frequency 
searching by using that fact.

Is that really the quickest route to success or is there a cleverer way?

Secondly: if I shift a frequency, do I have to stay within its bin or 
otherwise add its volume to another band?

Can pvsmaska or pvstencil be adapted to quickly pitch the masking/filtering 
function instead?

Thanks for any good suggestions, pointers and hints on the above.

Best wishes,

Jeanette

Hi,

check out opcode partials from the PVS family!

I already had. I does sound interesting. Can the output of partials be
used with normal PVS opcodes again, or are these signals limited to the
track specific opcodes?
...

Best wishes,
