Disklavier

Hello all,

We are new to player pianos, but do have good computer knowledge.  Our 
Player system moves the keys with the disks (commercial) we received 
with the piano, but the midi files we have downloaded and copied to 
diskette do not?

We have tried to change track, and SMF types 0-1.  Probaby could 
stumble through it some more and find the answer, but thought we could 
save some time by asking the group of knowledgable owners what we are 
doing wrong.

The midi files we have downloaded are supposedly for the disklavier, 
so they should have the info required for the keys to move?

Thanks for helping.
