While building my extended VSL presets, I can see that the best results are achieved by alternating articulations for the same playing technique. For example, a staccato can be played by a Staccato, a Détaché Short, or a Martelé sound, depending on the context and the phrasing.
In Logic, you simply select the appropriate articulation for the Articulation Set list. In Dorico, one would need different playing techniques with a similar look (for example, different Staccato techniques, all looking the same in the score).
Or, is there a way to overlap the base sound indicated in the Expression Map, with an alternative playing technique not appearing in the score? Maybe something only appearing in the Play lanes?
