I would love it if the FX would get a tail when you turn them off, similar to when you pause a track while an effect is on.
I’ll use echo as an example:
When I turn off the echo effect, the effect is immediately gone, just as if I had turned the dry/wet dial all the way to dry.
When I turn off the echo effect, the effect plays on with the input it had until that point, the same way as if I had left it on and hit “Pause” or turned down the fader.
This has been suggested before in the old forum: FX Tails instead of cut off
