hi daniel
can you tell us where you found the referring theory? does the theory mention the delay in the feedback line? since you only can achieve a feedback loop by using a [s~]/[r~]-pair you normally get a delay of 64 samples in pd.you can de-/increase this value by setting a different block size with the object [block~]. i can only assume, but i think in such an unstable system the delay may plays an important role.

Hi. im simulating single carrier FM feedback. Im modulating the pitch of an osc~ with it´s own output: *Im multiplying the output of the osc~ with a fader that goes from 0 to 1000. *Thar result im adding with a fixed frequency. *and then back to the main freq of the osc~ object
this is very simple, according to theory i should get an increase in the partials (which im getting), but im also getting a pitch shift in the main freq of the oscilator as i expand the amplitude of the feedback!!! I can´t see why this is happenig, i think it is not supposed to happen. Can ayone explain to me why this is happening and how can i avoid it?
thankz
