Plus following the setup described - the Keylab sends regular mysterious midi signals to Cubase. These stop when keyboard is unlugged or Mackie HUI is removed
I've been trying to set up Cubase VST/Track Quick Controls with help from Arturia technical support and they have so far been useless!
Sorry to vent
I've started a new thread for my own specific personal issue relating to Cubase Setup here -
