Comment 16 for bug 1481170

I agree, I would hardcode a long fadeout time and let the user use dry/wet to shorten it. (Keep in mind not every effect needs to take that long to fade out, it an upper bound)

Daniel's approach of sending a signal to the effect is better than just reading the effect's flag and cutting input and fading output. If we tell the effect it has to fade out, the effect can adjust itself to try to fade out on time, thus avoiding the hard fadeout. For example, an echo effect could automatically decrease it's feedback parameter if it is too high.
