Would someone please point me to MCU protocol reference used in Cubase 10?

Hello,

I’m trying to figure out what the buttons on my Presonus series 3 do when sending MCU messages via DAW mode. The faders work, the transport works, then there’s dozens of buttons that do random things, but no real way to figure out what Cubase is doing with those messages.

Would someone please point me to a reference of how Cubase interprets MCU messages?

Would someone also please point me to the protocol reference for MCU? I can’t seem to find it on google.

Thanks,
Nick
