I got since a while Cubasis 2 and I used on iPad Air successfully, with my Allen & HeathZEDi8.
Now I got the iPad Pro. Cubasis is running, it detects the ZEDi8 but no audio is taken from it.
To be sure the ZEDi8 is working, I used it with Garage band (that comes with the iPad Pro) and it’s working fine.
But with Cubasis 2: no audio is listened nor recorded :-/
I did already all the steps that the video suggests, with not any result.
To be able to make it work, I had to uninstall the App (previously installed from the Cloud … 'cause it was installed on an iPad Air), and fully re-install it on the iPad Pro
At that point it worked.
