When you fade in or out the track that has the FX plugin still remains the sound.
eg) I made fade in and out for the drums track that has reverb. The track makes the sound even though the automation level is completely at the bottom. The sound comes from the FX channel.
I tried it with Mixtool, but it still has the same issue. VCA channel can solve this issue, but it ruins the fader level, so it's not a perfect solution.
Therefore, I request the separation between the automation and the fader. Or something else you can solve it.
