I’ve tried to connect my UR22 mk2 to my iPhone XR using an official Apple Lightning to USB adapter, the interface is detected in Garageband on iOS 13.3 but the sound I get from both inputs is absolutely horrible!
It is unusable in any way, hear for yourself (attached) Mon morceau.zip (229 KB)
I’ve tried to change inputs
I’ve tried to change USB power supply
I’ve tried both mic and instruments (electric guitar)
I had the same problem with my unit on my laptop. I finally got it sorted with customer support today. There’s firmware on the actual UR22 mk 2 which has to be updated. One of the patches supposedly fixes that issue.
