Hi,
VelXF presets require CC1 for controlling dynamics. You can use CC28 to turn the VelXF control on/off.
I created articulation sets for Logic and expression maps for Dorico with automatic switching of CC28 depending on the articulation (modulation for longs, velocity for shorts).
If I want to use my maps, and at the same time use either velocity or modulation for everything, I don't need a new set/map without the automatic CC28 switch. I can simply replace CC28 with something else, like CC29, in the player. CC28 messages will therefore be ignored, and the status of the VelXF switch will remain the one I chose manually.
