Hi, guys I am trying to make a square wave from Sines, however, I think I am getting the phase wrong. As you can see in the scope, it's not a square.

Could you please point me to an example. The max documentation seems to only have already made objects like rect~ phasor~ and so on. Thank you

phase needs to be 0.25. because cycle~ is a cosine not a sine wave.

depending on what you do it could be cool to start from a phasor~ and make all waveforms from there.

once you did that you will know the phase relations between these methods by heart. :)

however i needed it to do it this way so so that students learn by adding each harmonic ‘s frequency and amplitude manually.

The phasor object gives me a made up shape already, also I am aware of the examples in the documentations thanks

multiplying sines can produce the frequencies needed since the output of the multiplication is the sum and the difference of the original frequencies.

you´re right, i misunderstood the question. 

you still could use phasor, in order to avoid phase offsets between the partials.

Hi all, I'm having the same problem, I would like if possible to understand why the phase needs to be changed and by how much it needs to be changed. Thanks in advance to everyone.
