iPad Air How to connect Ipad air 5 to midikeyboard?

[Museo12]

I have a older midikeyboard with usb-b cable. The Ipad air gen 5 has a USB-c. But I think I need something more than a USB-b to USB-c cable. Something that can ”drive” the keyboard. But what?

A powered hub if the keyboard doesn't have a power supply. Something that also allows you to have an Audio out signal.
