Is it possible to plug an iPad into the usb host port with the camera connection kit or the usb 3 lighting camera adapter? I want to use lemur to control ableton on an iPad pro 10.5 inch plugged into a Play Audio 12. It seems like most people use a midi 2+ or 4+ with the lighting cable. Just not sure if that's necessary. Any help would be greatly appreciated. I am excited to work this tech into our live tracks rig.
