Well don’t go rushing out to buy a new iPad for Cubasis 3 just yet. I wouldn’t feel bad at this point that you can’t run Cubasis 3 because Cubasis 3 is very bug ridden. Cubasis 2 is by far the better of the two right now for getting any serious work done. Also my iPad running IOS 12 (12.3.1) is still a smoother experience than my other almost identical iPad running IOS 13 (13.3) If they can get all the bugs fixed in Cubasis 3 I’m still not sure it would be worth getting a new iPad for … its still missing basic rudimentary features like tempo/time signature.
