However, if you wish to invert the phase for a given partial, simply prefix it with a '-':
sinesum 256 1 -0.5 0.333 -0.25
for instance - each negative partial is flipped 180º.
(Too bad there's no way to make intermediate phases with such a simple statement - you'd have to do that by hand with a counter & a formula.)

Hi, I'm a relative newbie to Pd. I have tried to build a patch that lets you create an array, summing partials at any phase/amplitude (as an learning exercise).
I kept getting stack overflow with my first attempt because my array was too large so i had to put a delay into the circuit. Is this a reasonable workaround or is there a better way?
Anyway, if anyone can suggest improvements to my patch i would appreciate it. I'm guessing someone will have the answer using half the number of objects.
My next step is to add some receive objects so that a message can be sent of the form: [; const 0.5; partial 1 0.4 0.7; partial 3 0.8 0.5 ( to set up an array in one go.
Cheers Garry. =====================================

Hallo, alexandre matheson hat gesagt: // alexandre matheson wrote:
does sinesum automatically offset the phase of each partial by 180º?
No, every partial starts with phase=0. You can see for yourself with:
sinesum 256 1 sinesum 256 0 1 sinesum 256 0 0 1 sinesum 256 0 0 0 1 sinesum 256 0 0 0 0 1 etc.
sinesum is just a sum of sines. ;)
