Disklavier

Greetings,

First post, just found the group....looks like a lot of experts on here, so I'm going to ask a novice question.....I've been downloading tons of great midi files from a bunch of sources after getting my E3 a few weeks ago.

I've had good results so far using the free midi sequencing software, Anvil Studios to reassign other midi voices to play on the disklavier acoustic keyboard (certainly not a great program, but free and fairly intuitive).  There is one midi so far that is giving me fits, though....one particular version of BJ Thomas's  'Raindrops Keep Falling on My Head" as downloaded on the link below, sounds great via computer and okay on the disklavier, except no matter how I try to resequence, reassign channels to CH1, CH2, etc....attampts to merge tracks, change voice to acousic grand, etc....after dozens of attempts using various tricks that have worked on other files, the disklavier will only play any assigned piano parts through the tone generator, not the keys....can someone take a look at the file and see if they can let me know if there is something in the file preventing the assigning of tracks to the acoustic piano?  Your input would be greatly appreciated!  Thanks much.
