I think I have seen that some users connect AVB capable devices (e.g. from Presonus or Motu) to the USB port of iPads and got full connectivity to the other studio setup via AVB networking. Some AVB devices are quite affordably nowadays. That would also allow for great audio routing setups in a gig I assume
I have a presonus audio interface. It works 100% with my ipad pro and has for years. But if I have to take an ipad and an audio interface and and and then why do I need an ipad at all? I could be using my laptop and have more options.
