I CANNOT OPEN THE APP with this dialogue
Oh. That's a new one to me. That error code looks funky. Tell me, do you use any external audio interface or is that with built-in audio only? Which version of OS X?
i had this exact same thing happen the first time i opened it up.
OS X 10.12.5
Traktor Kontrol Z2 selected as my system audio out
Same error as OP posted.
Changed system audio to "Internal Speakers" and the app opened up no problem
i then changed the Microtonic "Device Settings" audio out to Traktor Kontrol Z2 and everything has been fine ever since.
