The Yamaha AN1x Synthesizer mailing list

I'm fairly new to midi and I am having a hell of a time trying to 
figure this out.

How do I get my mpc 2000 to change the sounds in the AN1X as it goes 
from 1 sequence to the next. 

I have tried to get this to work but so far I have had no luck in 
figuring this out.

Any help will be greatly appreciated.
