Cubasis & Combo madi usb Soundcraft

I have a doubt, we work with sound souncraft SI mix and recently purchased new card Combo Madi SB for souncraft.
and I will connect the Blast happened to ipad with Cubasis, to see if the detected and what my surprise that detects all input and output channels.
The problem is I can not write to the Cubasis, because I just record a continuous sound of the first note he enters play. The strange is that it detects the card will be played even earlier projects.
Indeed it is the ipad2, work with the Air2?

Thank you very much and greetings to all
