I'm learning registrations..

When I call up my registration (001, Blues Brothers) from the block, I see the Registration name, the drum pattern and the voice, all loaded up. This is perfect.

When I call up the next registration (002, Black Velvet), I get that song and it's drums etc.

BUT, when I call up 001 again, I get the blues brothers registration (the voice), but the drum pattern is still Black Velvet. What's going on here?

Thanks,
Jarlath
