A trick I was thinking about, to control dynamics in Dorico. My recent maps (for BBO and SynSE) all include a CC28 value as the first message of a technique in the expression map. I’m forcing each technique to respond to either velocity or modulation.
This is the easy way, but also the least flexible one. It is true that most of the time it is better to control shorts with velocity and longs with modulation, but you might sometimes prefer something different (for example, when improvising at the piano keyboard, or when wanting to draw curves for shorts).
With notation programs like Dorico, another way could be creating a couple techniques "VelXF On" and "VelXF Off", with different values of CC28, and add them in the score just before the passage to be controlled one way or the other.
I don't know if this might, in the end, become too time-consuming and annoying, but it's an easy-to-use switch if you need to work this way.
