FIGURED IT OUT!!!!!!!!!!!!!!

Anyone interested:

1. load in your .SET from (my case, the 3X)
2. Select any song from your list
3. DO NOT HIT THE DRUMS YET
4. Go into Write on Songbook and DISABLE 2nd option on page "keyboard set"
5. Select 1st option on page and select "STYLE/SONG" and select which is the correct drum for the song.
6. Simply save and done
7. Of course, some of the sub drum categories, FX, volume and other parameters can be changed then to match up.

I believe this is going to work and will let you know if I run into a snag, but this pretty encouraging.
