Disklavier

I own a Disklavier Piano model MX-85 P which comes with a Disklavier Control Unit - DKC5R. 
It uses the 3.5 " diskette to play the piano. I want to know if there is a way to upgrade this to 
a newer control unit or have some modification that can be controled from a computer. Be 
aware I am new to this and I am looking to get rid of the floppy. I have been able to create 
floppies in the past to play on the piano but ... the technology is very outdated.

Any thoughts,

Jay Wagner
