Hello, Sorry to hear about your troubles with Analog Lab. I am curios if you have tried using analog lab with a generic controller? I have been using analog lab with a Alesis Q25 and it hasn't crashed at all. In fact this is by far the most stable product I've seen from Arturia yet.
Obviously you want to use your Arturia controller but it may help troubleshoot your issue. It sounds to me like you have defective hardware that is causing a MIDI conflict and crashing. Whats it say in your console log right before the crash? Also, contact Arturia tech support they will help you. ( and be nice)
Try downloading a free MIDI monitor app and move the controls on your Arturtia keyboard while looking at the messages, do you see any inconstancies? any skipping of controller numbers changing direction ? stuff like that.
Good luck everyone.
