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

…yeah, things started breaking again. Really hard to say what triggers it, just after building a new template for a while, it all starts falling apart.

Steinberg, please look into this. Here’s two track archvies for Omnisphere - 1 instrument track, 7 midi, all outputs activated. This one opens cleanly

This one opens broken:

Here’s what I see when opening the broken version:

(with another 6 midi tracks below which are fine). The output order is messed up, and there are duplicates of G and H (also without their colour info). This archive loaded fine yesterday, and is broken for me today loading into a blank project.
