Problem with Creating Expression Map entries for Muted Brass for BBC SO Pro

Hello @dko22,
You can find a tutorial using VEPro with BBC SO in Dorico here:

The difficulty in providing a VEPro file is that it is quite personal as you have to define (and so load) a set of instruments in VEPro.
You can use all the instruments or a subset in Dorico, but it really depends on the instrumentation of your score, and if you want to have a big general template in VEPro (depends on your RAM) or a different VEPro file for each of your scores.

I hope that helps!
Regards,
Gil.
