Recording Cubasis 2 into BeatMaker 3

Happy New Year to all readers.

You used to be able to route Cubasis 2 into BeatMaker 3 I think.

But now cannot do it.

Tried AUM and Audiobus too…no luck. Audio or midi.

Not sure if it’s due to iOS 13 or what?

I have I pad pro 2017 12.9 model.

Cubasis has been really buggy when editing audio…and BeatMaker 3 offers more options here…but I’d love to use Cubasis 2 Waves effects into BeatMaker 3 as not that great effects in BM3, and don’t have many audio unit ones.
Of course I could export stems from Cubasis.

Help much appreciated
