Question: Setup iPad as effects processor for MacBook ?
So, up until today I've basically had two audio interfaces - I run my guitar and vocals into my iPad via an Alesis iODock, then took the main outs from the dock and put them into the inputs on my Scarlett4i4 which is connected to my aging MacBookPro. Good news: got a new iPad Air. Bad news: USB-C means I can no longer connect to the iODock because that all is hard-wired.
So, my question: Do I need two audio interfaces in order to run my guitar/vocals through my iPad and then out for streaming? Is there a way I can (I'm making this up) connect the iPad, Scarlett, and Mac together on hub, use the inputs on the Scarlett but route audio through the iPad to handle the DSP, and then emit that out to an OBS live-stream on the Mac? Specifically, I need to use the iPad so the DSP doesn't hit my Mac's processor because that gets pretty eaten up by the streaming.
Any thoughts on the setup or am I just gonna have to buy a new class-compliant audio interface?
