I hope this is in the right forum - please move to the correct forum if necessary.
I'm trying to help my brother who is a moderately experienced musician, but not very tech savvy.
He wants to learn how to make music on his iPad and/or iPhone, preferably with GarageBand. He first had an Android tablet, and I showed him how to use its microphone and an app called BandLab, which he managed to get the hang of, but he's used GarageBand in the past, prefers it and now that he has Apple devices, he'd like to use GarageBand again.
I want to help him set up his iPad Air (3rd Gen) to record his guitar, singing, keyboard etc. directly to GarageBand without using the built in microphones on the iPad Air.
This Youtube video explains what I want to do: https://www.youtube.com/watch?v=4LlQkBY5HII
I've been told that the best way to do this is with the official Apple Lightning to USB 3 Camera Adapter which costs $65 AUD plus a portable audio interface such as a Focusrite, which I have no knowledge about whatsoever.
The reason I'd need the Apple Lightning to USB 3 Camera Adapter is because the portable audio interfaces need power from the extra lightning input on the Apple Camera Adapter, it then uses the USB input to connect to the audio interface. I hope that made sense.
I'm wondering if anyone here has any experience doing something like this, whether there are any cheaper options than the official Apple adapter, which isn't that much TBH and I know how finicky Apple can be without their genuine products.
The main bargain I'm looking for would be a decent portable audio interface that will work with the setup I've described above. I don't know anything about these audio interfaces, so any tips or recommendations of decent and reasonable inexpensive ones would be very helpful, I'm happy to buy refurbished or second hand, if the discount is good enough, so long as there's some kind of warranty.
Also, I'd be happy to hear any other advice, or options I have, or perhaps other ways to get direct instrumental input into an iPad or iPhone without relying on their built in microphones.
Thanks in advance.
I suggest you head over to r/ipadmusic. Please consider Logic Pro in preference to GarageBand.
