We had no issue with S4 last time we tested it.
But in the past, there had been issues where the controller stopped working when receiving too many MIDI messages... Kinda weird, but might be a NI defect to prevent 3rd app to optimally use it... This had been work-arounded, and never happened anymore since then.
I don't know if it's the same issue, but might be...
To check it, try turning off (unchecking) MIDI OUT in MIDI preferences, and let me know.
Thanx.
