Since you're new there's a few things you should know, ok well just one thing. If you're looking for help with a patch, or trying to solve a problem with your patch, post what you have so far or an example of what you're trying to do. In Max goto Edit > Copy Compressed and paste that in the post, this not only helps us understand what you're trying to do, but often times people can copy your patch, program the fix, and post the fix.

For your specific example, I'm not sure exactly what you're asking. Are you trying to change the bank on a physical midi controller? Or are you just trying to load a voice that's on a different bank?
