I'm using VSL SSE, Finale 25 and Dorico 3.
As a general question, first: I don't understand the relationship between Expression (cc11) and Velocity cross-fade (cc2 by default), if someone could patiently explain that to me.
Specific question, though, is how to set it up in Dorico 3. I can choose between note velocity & cc, and also enable a secondary choice, also velocity/cc. Do I want to make one cc11 and the other cc2, or should I stick with velocity in one and cc in the other, in which case, do I want cc 2 or cc 11? There doesn't seem to be a way to have all three simultaneously.
