The mute button cuts off the sound for the (all the) destination(s) the bus is connected. The solo button cuts the others ( from the destination point of view.
That is a little bit tricky when more than one destination is selected.
Is there a way to tell on which one they will be active or to get one button by destination
Excuse me I didn’t really follow you. If I right click on the solo or mute buttons, I have a solo lock option, and I have options to pre post to tell where to mute.
I don’t have the choice to mute this or that destination if the output ( on the bottom ) is connected to many destinations
the solo, of course mutes the others, but it mutes all the other buses. If I solo a track, it mutes the other tracks ( I even set the options to get in light yellow the mutes due to a solo ). I would like also to customize that.
