Hello Lars,
thanks for your support, but this was not the problem. My ipad2 had a defect with its audio input. Meanwhile I upgraded to the latest iPad but things get worse!!
It seems that nothing is going through the audio connector, neither way! But the ZEDi10 is recognized by Cubasis LE. I’m using the original apple camera connector that features an extra lightning input. Can you provide me any hint? BTW, I have checked: MIDI works well and the iPad internal Mike works fine, too.
Hope you can help!
Roland
