Port routing issue for expression map Init-type actions

[dspreadbury]

I remember a related problem being reported before, e.g. this one:

Dorico sends "on init" and "all notes off" messages only on port 1

I’m working with a VEPro template that uses multiple ports and noticed that “all notes off” message seems to be sent only on port 1. Please correct me if I’m wrong, but I seem the get consistently different behaviour on port 1 and all other ports. Same applies to “on init” entry in expression maps, it seems to only work when the instrument is on port 1. To clarify, I added a control change (CC13=100) to “on init” and it only worked when the instrument was on port 1. I would need the “all note…

I don’t think we have changed this in Dorico 4, so I suspect Dorico is still only sending these INIT messages on port 1.
