Hi i'm trying to reset all tracks to the default volume together

but when i select them all and i double click on a single track it doesn't reset all of them

how do i do it?

i want to bring all levels back to default

 

On a mac on most daws it's either holding alt or holding cmd and clicking. (I can't remember off-hand!).
This brings faders to 0, pan to 12 o'clock, etc.
This is usually universal just as cmd c or cmd v are for copy or paste.

 

Make sure you have SWS Extensions installed.
Under the Actions menu select Show Actions & type reset volume into the filter box.
Select & run Xenakios/SWS: Reset volume and pan of selected tracks.

From there you can map/create a shortcut to perform this action when needed.
