Okay I’m going to answer my own question, sort of.
There was something wrong with the instrument track. No idea what. I finally just created a new track and that one worked. I otherwise see nothing different about the bad and good tracks.
Having a similar issue. SD3 standalone player can be triggered by my Roland TD-12. And for several days, I could trigger SD3 when it was in ProTools, latest version, so everything was fine.
But now, SD3 via ProTools cannot be triggered. I have checked all over every setting.
I’m on Ventura on a new Mac Studio
