Disklavier

Good evening to all!  I have a DKC100xg that we play using sweet midi on our iPad.  It works great!  We are trying to find midi files of contemporary artists to add to our collection.  We hear beautiful piano music on pandora, note the artist, look up their website and we can never find midis we can purchase that will play on our setup.  Is there a source for these types of midi.

Thanks,
Ed
