I've done MORE than due diligence hunting for answers to this question, and NO ONE in the NI Community will answer it. I want to know if KK 2.9.6 will cause conflicts in this set up. I'm not using the S88 to "drive" anything per say. I just want it to play, and respond to what I have dialed in on the S49 that's using KK 3.3.1, or whatever the latest is for that.
