Has anyone been able to use synthstation 25 via the USB connection through the camera kit? I tried using 2 different powered USB hub and it does not work for me. I have been using a iOS dock extension cable so far, but only apps that support the synthstation 25 works. Puzzling is that the akai synthstation 25 works with my apple computer via USB, GarageBand and reaper. Something is not right. Iosmidi said it would work with powered USB hub though.
