Rikki,

There is a drum conversion tool in OMB. It is in the Stylemaker window in the menu tracks/convert. You have to define in a table which note has to go where. In the same table you can also adjust the velocity of each note.

I'll try if I can make a conversion table for the standard drumset in XG. I'm not sure if all sounds have suitable counterparts in the GM range though.
