The phone likely does not provide sufficient power for your sound cards and keyboards. If you get one of the camera adapters that also has a power connector you can even charge your phone while it’s connected to the hub.
I am contemplating switching from macbook to iPhone (xs, with lightning port) to use Pianoteq with my midi piano. I've been reading up in the last few days, and I think I understand what is needed now. Apart from the camera adapter (which has only one usb-inlet) we need a usb hub to be able to plug in both the audio interface/dac and the midi-to-usb converter (coming from the piano). I also understand that the usb-hub needs some power (like you also state) to feed the audio interface/dac.
However, in a video I found (admittedly an older one) this guy says that connecting the lightning inlet on the camera adapter to a power source (which would then also charge the phone), would be sufficient to álso power the audio interface (in his case a usb-powered Scarlett).

This suggests that the usb hub that comes between the camera adapter (with usb + lightning port) and the audio interface/dac does not have to be a powered hub, but can just be an unpowered one with two inlets (which is a lot cheaper, and likely also less prone to buzzing and things like that).
So I'm a little puzzled here - could you perhaps shed some light?
Cheers!
