What's happened is ....
No matter what Articulation is showing loaded in Vienna Ensemble Pro / Synchron player driven by a track in Logic during playback of all ready recorded material as soon as I play a note from a keyboard, Synchron player calls up the Short Notes Staccato patch.
I'm no longer able to play anything other than Staccato notes in real time.
I'm lost as to what parameter controls this. (obviously I'm not playing any notes associated with Key-switches)
