Thanks! Loopy Pro uses my audio interface and I have plenty ins and outs there to my mic and guitar rig… I’m not sure how iOS works or if two apps can use audio at the same time. That said, I’m not using the internal mic on IPad just to be clear, but want to make sure that nothings interfere before I buy. The background mode is important to me. Audio controlled by mic input not so important since I will automate that on my pedalboard and send midi messages at the same time a song enters a new state in my live looping show. But as far as I understand there is no on/off switch for that and mic input need to be always on for background to work?
