Using s88 and noticed it has a 2.0 option. Switched, rebooted, deleted midi controls and the keys won't produce sound in either Logic or Ableton. Switch back to 1.0 and they work again. Apple says they're compliant. NI says they're compliant. I don't know who to to trust but one of you is wrong and/or needs to provide more documentation on how the switch from 1.0 to 2.0 is done without crashing the DAW.
