Playback solo issue

I can’t get staves to solo in playback.
I have 8 staves/tracks and when I hit solo on one track, all of them solo as if they where grouped.
The file is coming form an xml import…

Same with mute.
alt-S doesn’t work either.

Any clue as to what I can do ?
Thanks

Could you please tell us more? What VSTinstrument do you use? NotePerformer?
Maybe you could take your project, delete all the notes, save under a different name and post it here.

The imported score launched with Note Performer.
Here is the empty file to reproduce the issue.

Thank you
All the best

Then it is clear. Note Performer has it’s own mixer and only presents a stereo output to Dorico. You have to employ Solo or Mute inside NotePerformer’s mixer to get the wanted result.

oh thank you !
