Disklavier

Would it be possible to play piano music in midi file format from my PC and the PC midi 
output connected to the MX100B midi input?. In this way it would mean I do not have to 
constantly change diskette but just using the PC large hard disk space build up a library to 
work like a juke box?.

It would be more cost effective and convenient even to allocate a dedicated laptop for this 
application. The DSR1 provides me with 1.44MB diskette and additional tone modules 
which I do not require. I merely use the disklavier for music playback only.

Can someone please advise me how I can do this.

Thank you
Frank.
