Anyone updated yet?
If so does Cubasis behave?
I’m probably going to try this weekend. 
Maybe it’s old news but I updated yesterday and Cubasis seems fine. At least with my selection of plugins…I’m trying to cut back … but in AU -GeoShred , EG Pulse and iSymphonic all behave. Animoog is fine as IAA after an update.
So far so good.
I’m on an original iPad Pro 9.7 inch.
