Help, multitrack audio routing issue.
I purchased a lightning to USB-B cable to run multi track audio into my Behringer XR18.
I have an older Ipad mini running OS13 with the last edition it will load of ST3, this works fine and when the app opens I can see and select the XR18 tracks to send audio to . I can hear the audio in the XR18. This is the version that has only 6 output tracks.
When I connect my newer iPhone and the latest version of ST3 it will just not see the XR18, the only audio output options are speaker L and R. I’ve tried starting the app first, the XR18 first, all the combinations but nothing changes.
What am I doing wrong? is there some setting in either ST3 or the iPhone with newer OS and App versions that I need to select to get the two to see and talk to each other?
I really want to use the iphone and have also been thinking about a new Ipad but I want to make sure it works first and at the moment it doesn’t!
Thanks!!
