My issue in the original post is a bit different:

1. I can force to MIDI drums and an appropriate MIDI drum will play on the standard MIDI drum patch.
2. When I try to select another MIDI drum preset, it LOOKS like the new preset loads (in this case dogsamba).

3. But the drum pattern that plays is the same one from 1. above, not a samba.

Really appreciate the time of all who have pitched in so far...THANK YOU!
