Drone,

What I would try is the following...

1) Save you song with a slightly new name and work on this newly named file. (This preserves the original file if you need to get back to it.)
2) Right click on the Drum track. (See image below.)
3) Select "Track Actions" and then select "Erase Track."

Save the song and regenerate.

This should clear the multidrums for you. You can then add whatever single drums you want to.
Doing it this way should give you a song file with everything that the original file contained except the multidrums.

Regards,
Noel
