[CAN-13042] Multi out instrument tracks still broken after disabling PLEASE RESPOND STEINBERG

Yes. It’s been pretty tortuous getting this far, but as of last week we finally have a case number, and the devs are finally on it.

I’d been getting increasingly depressed about it. Track Archives and Disabled Tracks are the two tools I want to build my new template around, but both are so buggy as to make the experience tortuous. Here’s hoping this turns the corner.
