Hi. New to the APP. I tried searching but could not find anything. Can I use a lightning connection splitter to 2 1/4" cables? I tried it but it would not work. But I wonder if there is anything I am doing wrong. I want to send the click to one of my XR18 mixer channel and the backing track to another. What I have seen in this forum is it works with the lightning to USB cable, but I would like to have my computer connected to the USB so I can record the band live. Help please.

Never heard about this type of cable. But I don't see why it should not work (well except it is damaged somehow).
Hi, I found this cable on Amazon: https://a.co/d/7Razubs
There is also a USB C version that I tried today and works well - but only to play iPad/iPhone into a mixer not the other way for recording etc.. So now I don't need to use the USB C to Headphone adapter.
