I'm using Kontakt 8 with the Spitfire Solo Strings library, in Digital Performer 11.34
I'm using key switches (with MIDI notes) to change articulations in the instruments (2 violins, viola, cello - Core Techniques). It works fine EXCEPT that Digital Performer's Event Chasing doesn't seem to work with the notes assigned to various articulations, although it works fine with MIDI notes that trigger instrument sounds.
In the Event Chasing window I have "Notes" selected which it seems should be what's being chased when I hit play, as the notes are MIDI notes.
