Hi,
In the players from VSL, dynamics can be controlled either via Velocity or via CC. This can be decided in the patch (articulation), or in a general way by using a dedicated CC (by default, CC28).
Some recent collections include presets with shorts controlled via Velocity, longs via CC. As an alternative, presets where control is decided on a general level are still supplied.
While I like to have shorts controlled by Velocity, I still prefer to have a free decision on how to do. When building expression maps in Dorico, the first event in one of the items is a CC28. In general, this is the same as having the type of control in the patch: shorts and longs behave in a different way.
But with the type of control delegated to the expression map, I can decide, on an individual project, to edit my expression map, and change how it behaves. If I want the shorts to be controlled by a CC, I can simply change that, and the preset will simply behave by consequence.
