First post here, i've recognize some quite famous persons here !
Anyway, i will present a short course on sound synthesis (my hobbie) in paris.
I ve decided to present different sound synthesis according to J.O SMith classification
I ve implemented simple maxmsp patches with temporal and spectral representation for each synthesis (patches are made for pedagogical issue, the goal is not to create incredible soundscape :) ). You can download patches here:
Does anyone have some critism about the patches ? Some idea to make patches more adapted for educational issue ?
Then, I ve a problem with my additive patch. In fact i would like to show how to obtain square, swatooth and traingle wavform by summing 6 sines (In fact this waveform need to have an infinite harmonics, but with matlab i ve verified that 6 sines can give good apporximation).
My problem is: " when i look to the oscilloscope, i don't obtain the correct waveform".
I believe that there are some phase problems ? How to synchronise the phase of each sine ?
Some idea ?
