OK I’m on the OT right now and I realise I made a huge mistake :
I scene-lock track’s amp VOL and not XVOL…
I’m a bit dumb there 
Gotta edit all the posts here where I was saying LOUD a wrong processus ah ah…
Thanks to you!
Edit:
I just checked and indeed XVOL scene-lock doesn’t override the VOL pLocks.
BUT, for the 2-scenes needed for XVOL duties, I can still say that you can do it with just 1 scene. I.e. using a scene with XVOL=MIN will “mute” the track. Doing it right now with no problem between inactive A scene and active B scene.
Cheers
