Have a dilemma. My keyboard (Yamaha MX88) can only connect to iPads (for using apps like Cubasis LE, FM Essential, etc) from the USB Host port on the keyboard into a USB camera adapter, and out to the iPad. If you try to go directly out of the regular USB port on the keyboard and into the iPad, it doesn't work. To be clear, you must go: keyboard USB Host port -> USB camera adapter -> iPad The problem is that the USB camera adapter only has Lightning out, not USB. I know this is a niche use situation, but has anyone surmounted it?
