I'm trying to input notes into Garageband app on iPad using the LK-300tv. The manual mentions General MIDI capability, and also about need to install drivers to connect to a computer. So far, I have the Lightning-to-USB camera kit cable on the iPad, and plugged into the keyboard USB port. Reading other posts, I configured the functions of local control to "off", and accompaniment output to "on". However, the iPad throws an error saying the device is not supported. Is there any hope this keyboard can be used with iPad?
