What are using for inputs into the iPhone. The cheap iOS sound cards used had no headroom and would distort way too easy.
Using rme soundcard in cc mode can help but I am unsure why you are trying to do that. Are you trying to record video on your iPhone?
More often than not you’d want the iPhone being recorded into the live. Moving your tracks over to a computer is a lot better than tryin* to record the output of the live into a iPhone.
Tracking out the live can be cool too but you need the right hardware, and running your stereo out into a iPhone just ain’t practical.
