Re: [sc-users] What is causing the audible clicks when the envelope is retriggered

I believe that the clicks are caused from the combination of the free running oscillator not being reset with your amplitude envelope, and the 0 second first stage attack. You're not starting at a zero crossing of the wave.

I removed the first stage of you amplitude envelope and the clicks went away:

env = EnvGen.ar(Env([0, 1, 0], [atk, rel], [c1, c2], 1), trigger, timeScale:ts);

I figure you have that extra stage in there for the retriggering to also have an attack stage (though I don't think it's necessary?), so not removing it, but setting it to be the same as atk also solves this:

env = EnvGen.ar(Env([0, 0, 1, 0], [atk, atk, rel], [c1, c1, c2], 2), trigger, timeScale:ts);

I also scaled it further down, there's a click but it's a bit more harmonically consistent...

env = EnvGen.ar(Env([0, 0, 1, 0], [atk * 0.1, atk, rel], [c1, c1, c2], 2), trigger, timeScale:ts);

I am trying to create a kick that cuts off when retriggered. The problem is that there sometimes are audible clicks when doing this.

Is there away around this?
