how to mute/unmute all tracks at once?

Hi,
In the Project window I put 10 tracks in the folder. I want to pres m in the folder and all tracks to react to that… to become mute.
If I press s - all tracks become solo.
So I want to switch between mute and solo in all tracks with one click.

I need this because the top track is a reference audio track so I want to jump between reference and my project midi tracks continuously.

Clicking on folder m & s button does not do anything to the tracks inside the folder.


In the mixer I tried to link tracks ( Add Group Channel) also do nothing when switching from m to s.

Anybody knows how?

Thank you!

did you reset the solo system once after the changes to the folders?
