Hehe, I didn't mean to sound like complaining. It wasn't too hard to find out and in the end seems to work like intended. Concern Midi Yoke problems I suspect that many users don't make that much use of Midi Sync while driving Live to its (sometimes easy to reach) limits or simply cannot identify the problem when Live behaves erratic. I can make Live crash in combination with Midi Yoke on a freshly setup Windows Installation even. But I found my solution and NKLive allows to change the setup if necessary, so I'm fine with it.
And I appreciate you pointing it out. If this did turn out to be an issue for other users, I would actually just eliminate using MIDI Sync output from Live. That only serves one purpose…to light the Play and Stop buttons on the pK.
