Is Mackie MCU protocol freely usable for DIY controllers?

Hey everybody,

I'm thinking about building / developing a MCU-based hardware controller for plugins. Does anybody know whether there's common knowledge about how MCU works in detail ?
And: Would it be "legal" at all to use the MCU protocol for own products without being licensed by Mackie ?

Thanks for any insight on this issue.

Thanks dpsbb for the link. I've read this one already - but since this information is more than 7 years old I was just wondering whether anybody had some new(er) insights....I mean there are so many DIY projects out there now with Arduino & RasPi, so maybe somebody could add something from experience in similar projects....?

MCU is 100% midi... it's not a "protocol" strictly speaking, but just a nomenclature of what control do what. I don't see any legal reason you can't build a midi controller that send the proper data to match MCU function list !

Look at they have a system to make all sorts of controllers. It might save you a lot of headscratching
