Hopefully someone can come up with an answer, what I ended up doing was copying all the parts into a new style (what a pain) and oddly, the Ritardando wasn't copied into ending III, but it *still* was on Ending II, so i reverted back to the version with no ending II, and re-recorded the drums from scratch, and then imported the instrument parts again, and *that* worked.
But that's more of a workaround. I was unable to find the sysex code for the ritardando
anybody?
