Re: Sv: Sv: What is causing the audible clicks when the envelope is retriggered

In all of the examples of hard sync that I've seen in SC, it's a linear ram=
p oscillator's frequency, modulating the phase of the synced osc, that sets=
 the frequency for the synced osc, which has its freq argument set to 0. I =
don't know what's happening in the lower level code mechanics that enables =
this, but it seems like this is what gives frequency
control to the phase argument.

In your example, the Sweep isn't doing anything audible that I can tell.. I=
 dropped in your original line of code and have been toggling back and fort=
h and no difference.
// sig =3D SinOsc.ar(freqSweep, Sweep.ar(trigger,freqSweep).linlin(freqA,fr=
eqC,0,1));
sig =3D SinOsc.ar(freqSweep, pi/2);

However, I did realize I made a mistake.. Sweep doesn't actually loop aroun=
d like Phasor does, it just keeps rising until the next trigger, so it need=
s a modulo to constrain it and force it to wrap around to stick between 0 a=
nd 1.

I'm going off this thread for reference:=C2=A0https://scsynth.org/t/fake-re=
sonance-aka-windowed-sync/2720/7. See jamshark's comments about phasor in t=
he code he posted.=C2=A0

Phasor actually sounds pretty wrong when I switch to it, but this is soundi=
ng more like a kick:
sig =3D SinOsc.ar(0, (Sweep.ar(trigger, freqSweep) % 1) * 2pi);

And also a very simple way to keep the range of the sweep between 0 and 2pi=
... since it is a value between 0 and 1, just multiply it by 2pi! Haha I al=
so got that from that thread :)

Anyway, still very different than your initial timbre, but it is starting t=
o sound like a kick drum again!
