Yamaha DTXpress/DTXplorer/DTXtreme

What I would like to be able to do is load a midi file into my module
(DTXTREME) or another synth module and make it stay in time with 
what I am playing on the drums.
I dont think the module has this feature built in but I was hoping 
maybe there was a box out there that could take a trigger send say 
from the kick drum and convert this into some kind of clock that a 
synth module would sync to.

The reason I would want to do this is so I could have a keyboard 
player lay down the horns and strings to a song in midi format that 
matches our version of a song. Then when I hit say a rim it starts 
the song and keeps in time with me and plays the horn parts at the 
right time in the song

Thank you in advance for any advice you may have!
