Hi Neil
Check out

1) S7S, OK, good. Although the pasting from another score may have brought undesirable items with it.
2) By fresh I mean, 
writing parts into a fresh copy of the Template - as opposed to pasting from anywhere else. You can also check your setup by playing back the TriggerTest and/or PlayTest files included in the package(s). If those are good, then the issue definitely resides in that specific problem file.
3) Again, pasting from another score can bring in unwanted bits, i.e. hidden MIDI messages. Be sure to turn on hidden objects and look at what is there.
4) What is the source of the wind parts you pasted in?
