In 9.5 I had the master I/O track visible in mixconsole (where I need it) and hidden in the arranger (where I don’t need it). In 10 this isn’t possible anymore.
Hiding a track in either mixconsole or arranger also hides it in the other. Is there a way to unlink this? And no, the setting in Preferences (Sync track selection) is about selecting, not hiding.
