What happens to the 4 extra pads from an mpc 2500 program.

If you have a program on a 2500 that uses all 16 pads in a bank and you load it on the 500, what happens to the 4 sounds that were on 2500 pads that the 500 is missing?

The first 48 sounds will load to the 500 from the 2500. So pad 16 is still the 16th sound which is located on the 4th pad in pad bank B on the 500. Basically you will not be able to play any of the sounds from the 2500 that are in pad bank D everything else will load to the 500.
