I cannot get my iPad to recognise my M-Audio Keystation 61es when it is connected through my Audiobox iTwo. The Keystation is running off its mains power supply, and its MIDI Out port is connected to the Audiobox iTwo’s MIDI In port using a standard 5 pin DIN cable. The Audiobox is connected to the iPad as normal (USB connections to a plug and the iPad itself), yet when I go to try the keyboard sounds in GarageBand (or, indeed, any other app that works with MIDI), I cannot make any sound or find the keystation in any menus. Does anyone know what is going wrong?
I should also say that the keyboard, interface and cables have all been tested separately and work fine.
