Disklavier

I recently (2 months) purchased a Yamaha baby grand with the disklaviere Dkc100xg. After replacing the floppy drive we have enjoyed many evenings of great music. I would like to be able to use a tablet (surface or iPad) to select and play music. I purchased a midi in and out to USB cable to begin the process. I am sure someone has put this system together and hope you would share your wisdom with me or point me in the right direction. I don't want to reinvent the wheel (lazy).
Any insight would be greatly appreciated.
