Reply to de activate control - a way to sync the volume manually

Problem
When i play around with FADER FX my volume sliders are usually left out of sync with the the actual volume level. And when i try to slide it back, even if really fast, it always sounds bad..

Possible solution
By pressing the shift button i could move the volume sliders without out sending the midi commands to change it. Thus i could manually change them to set the according to what i'm seeing on the screen?

Comments? any other ideas? is there already a fix for this?
