Hi,
I currently have a USB-C keyboard (Akai MPK Mini), which I can play through my iPad using the camera-connection kit. My iPad has a Lightning cable input, and the CCK seems to power the Akai keyboard just fine.
How can I play the Akai MPK mini when my iRig Pro Duo is connected? The "midi" input on the iRig Pro Duo is through an 1/8 in jack (?). I have no idea how to go from the Akai USB output to a MIDI connection, particularly if the Akai is expecting power.
