hi i'm new on pd.

i wanted to make sawtooth wav with sum of osc~ objects base on

t) = sigma ( 2sin(2*pi*k*f*t) / pi*k )
k = 1 to infinite.

i tried 10 osc~ objects to make it. but i think their phase are quite different.
so i want to ask how can i make them start oscillating at once or synchronize their phase. if you help me to solve this problem, then maybe i can make triangle wav and square wav also. thank you

hi minz,
you can set the phase on the right input of [osc~]. The range is scaled from 0 to 1 (0 - 360 degrees).

Hi minz,
the [phasor~] object is an already done sawtooth generator. Just in case you simply need a sawtooth.

To add, [osc~] is a cosine oscillator, not sine. So to get a sawtooth shape, you'll need to sync their phases at .75, not 0.

thanx a lot!
