Yamaha 01V and Cubasis ADAT Interface

Can anyone help me figure a way (inexpensive as possible) to connect my Yamaha 01V digital mixing board via ADAT optical cable into Cubasis on an iPad 2?

My original setup in 1999 included the Yamaha 01V with an ADAT light pipe 8 channel digital I/O. I interfaced that with a Yamaha DSP Factory sound card in my PC then into Cubase VST 24. It gave me 8 channel all digital I/O from the board right into Cubase. State of the art for a home studio in 1999.

I’d love to use the Yamaha with Cubasis but am stuck on the ADAT interface into the iPad.

Thanks in advance for any and all suggestions.

BTW just beginning to play with Cubasis and am impressed with its capabilities. Good job Steinberg.
