I've been trying to make a square wave, but my pd knowledge is a little rusty. I know of osc~ and phasor~ for a cosine and sawtooth wave, respectively, but I haven't been able to find a square-wave generator. I think I ought to be able to use an osc, and just output 1 when the output is positive, and -1 when it's negative, but I've become hung on the details. Is the following a good overview of what needs to be done?
osc~ -> snapshot~ -> moses 0 -> b (one for each moses output) -> -1.0 or 1.0 -> sig~
It seems like using snapshot to turn every sample into a number so that moses can divide them around 0 is inefficient. Is there an object that deals with signals that can do what moses does? (Or just a better way to get a variable-frequency square-wave in general?)
There are severaly ways. Attached is a non-antialiased version with pulse modulation (PM on hardware synths)
