The Slate Raven MTI is a phenomenal tool for mixing and mastering within any DAW.
However, This issue lies with MCU protocol.
The Slate Raven MTI takes up 3 out of the 4 Slots of your Control Surface Setup leaving the Faderport in a purgatory like state of non-functionality.
Connecting 2 Mackie devices in Logic causes conflicts with the Faderports implementation... the unit does already have a somewhat limited functionality in Logic..
Long story short, if you're gonna use the Raven, use the Raven..
If you're gonna use the Faderport, then ensure that the Faderport is the primary Controller.
