I want to do a patcher that takes, as input :
* a soundfile containing a constant pitch note (of pipe organ)
* its fondamental frequency f0 in an input box
It should give, as output :
* the signal which is obtained with the soundfile, by keeping only the harmonics (multiple frequencies) of f0.
Thanks a lot in advance, I don't know how to design this in Max/Msp.
PS : I.e. it will give something like the sinusoidal part of the sound (which is of constant pitch).
