As many of you other I often use delay feedback and say release time to make a transition. Is there a way to just increase the feedback of the delay of the track to a performance knob?
Or is it that the settings of the fx track cannot be set to a performance knob?
You can try to lower the delay send level of the other tracks, while increasing feedback on FX track and the send on the track you need.
FXs are global, they are not individual for each track.
