In fact, it’s much more problematic than it sounds.
Imagine you request an autafade out.
And when it’s started, you stop it.
The loop’s sound level is no longer at a normal level, yet it’s not mutated…
As there’s no fader, it’s impossible for the user to know what’s going on.
This is an example, but there are many other cases that will be problematic…
So, to do this kind of thing, you have to fade out using the track volume faders, and that way you can stop it whenever you want, and the level you’re at is visible by looking at the fader status.
