Do you hear them?
yes. erm, wow I have to admit I'm stumped....goes against all my previous learning.
I tried this and got a zero at 2205 Hz, which is exactly 1/20 of 44100, so it is definitely aliasing with the sample frequency. I assume the [>~] object is processed at the sample level and not block level, so then the noise is coming from the desired step transitions occurring 'in-between' samples. This could be overcome by interpolating the two samples around each transition point, but definitely there is a need for a sqosc~ object that would do that internally.
