UR44 - iPad - Midi Controller Connectivity


I am currently using a UR22 MKII interface with an iPad Pro over a Lightning to USB 3 Camera Adapter via a powered USB hub. (The USB hub is necessary to allow me to connect my USB controllers to the iPad in addition to the interface itself, and the system has been working very well.)

I now want to upgrade my interface to a multiple output iOS-compatible interface such as the UR44 or UR44C.

My question: Can I replicate my setup using the UR44 or UR44C interface? I need to connect my USB midi controllers to the iPad via the interface and, other than using a USB hub, I am not aware of any other way to achieve this. Can anyone confirm that this is possible on these interfaces?
