1: You can create a rectangular wave by subtracting two sawtooth waves
that have different phases, vary the phase difference to change the
proportion of high and low in the wave, at a particular phase you have a
2: You can [clip~] a cosine wave, various amounts of pre-clip
amplification change the "hardness" of the square wave. The Zexy
library also has [>~].
3. You can use tables with [tabread~] or [tabread4~] (there is also a
table osc but I've forgotten its exact name).
phasor~ is not band-limited, which means aliasing distortion can be
audible, if you're using it as an audio oscillators. I think there are
band-limited oscillator LADSPA plugins if you use Linux.
