What changed in the MPC500?

The only manual I can find is for version 1 of the operating system, so it doesn’t include the hp and bp filters, and it makes me wonder what else changed over the years up to version 1.31. Is there an addendum manual available, or an OS history update anywhere?

For anyone else needing this information, here is the update history:

Original manual should still cover everything you need to know. You can also purchase “Beatmaking on the MPC 500” from this site with more in-depth and updated info.
