I'd like to use the Reset All Faders command in the Environment window, but after selecting the tracks and clicking that I get nothing.
Let's clarify that first cause I do not see an right answer yet..
The "Reset Selected Faders" Environment command is probably quite old and it is a typically Environment one. What I mean is that it reflects only on Environment fader objects.
Example:
Create a few new Environment fader objects, set them to different definitions etc and different values.
Select these faders and use the "Reset Selected Faders" so all faders will reset to 0, does not mater if they use different definitions. This does not matches the Channel Strip Audio Objects !
Well, lets focus on the channel strip behavior now...
Select all channel strips you like to reset grab the most louder fader get it to infinity down and Option click it to reset all.
