Babylonwaves has released Art Conductor, an addition for Logic Pro X which enables time line based articulation switching of orchestra instruments. The articulations show up with their real names overlaying a part like any other automation lane.
The script was designed especially with musicians in mind and requires no technical expertise to be set up for a specific instrument. It supports both key switching by MIDI note and also Spitfire UACC controllers.
A special version (which is included for a limited time) supports Spitfire instruments right out of the box, all UACC articulations are already there.
