Powered USB hub with Pyramid/iPad

Does anyone use Pyramid to sequence iPad synths?
I would like to try, however I realize the USB cable is used to power the Pyramid. So I assume I would need to get a powered USB hub to make it all work. Plus, I’m guessing there must be different inputs/outputs for the hub as well so all the signals are sent/received.

Thanks in advance for any help!

Hi there, I send midi to the ipad (moog model 15) via the Korg PlugKey cause I wanted to have proper midi in and audio outs at my Ipad. Can’t tell you whether this could work with a camera connection kit, hub or similar as I stick to midi cables connecting the pyramid and ipad.

it works with a camera connector and IPAD (or iphone) and the apple device provide power to the pyramid
