Just to be clear, the articulations are triggered by keys right? I've used the Scarbee Funk Guitarist which works like this, and Session Strings Pro. All of those seem to work fine for me. You should be able to see the switches even in PRV (which seems simpler than event viewer just because they are usually in the lowest octaves).
Correct, Session Strings Pro and Scarbee work fine for articulations, its just Spitfire thats the main culprit (some of which are triggered by velocity)....The resetting volume control is bugging the life out of me today, its now doing it on Evolve....
I'll have a wander over to the NI forums methinks.
