Hi Benoit,
Since square is for alias-free oscillator usage. I would recommend
lf_squarewavepos() for a modulated gate:
import("stdfaust.lib");
pulsedOsc = en.asr(0.35,1,0.35,gate) * os.oscrs(freq) * gain
with{
freq = hslider("carrier freq",250,100,10000,1) : si.smooth(0.999);
freqm = hslider("modulation freq",2.5,0,10,0.001);
gain = hslider("gain",-10,-100,0,0.01): ba.db2linear(_) :si.smooth(0.999);
gate = button("gate") * (os.lf_squarewavepos(freqm));
};
process = pulsedOsc;
