Looking for a MIDI interface

Hardware and Accessories

Hi all,
I'm currently looking for a MIDI interface that would let me connect my Jamaha keyboard to my iPad Air... I'd like to use this in conjunction with the Alchemy Mobile app so that I don't have to rely on tapping the right keys on the touch screen... :-)
Are there any such interfaces out there that anyone here would recommend?
Thanks a lot for any advice on this! :-)
