Saving MPE data to a midi file?

Howdy! I’m just about to embark on some exploration/research and I figured I might start by asking here. I’ve looked through the MPE specification and it doesn’t say anything about saving the data to midi files. I am wondering if anyone has any knowledge about whether it is possible or not? I understand that part of the MPE spec involves stuff that is determined at run time, such as channel assignment, but I don’t think that would limit being able to save the data.

If anyone has any experience or expertise, please help!

Thank you!
