importing from MPC REN to PRO TOOLS

Vegas can, Reaper can, etc. If you import a sample that mismatches with
the project sample rate it will be sped up or slowed down (this can happen in any daw). Also, op can just convert the sample(s) to the matching sample rate of the project (destructive).

You can't change PT's sample rate on active projects, you need to create new ones with proper sample rates right from the start. Also, other DAWs occasionally allow changing them while the project is open, although I'd never suggest that. It's best to make sure which sample rates properly apply and work with them right from the beginning.
