It’s easy. You probably have to load the driver for the MCU (not sure if it has one) Then go to your device panel, add a Mackie MCU and associate the ports to the ones going to the MCU.
You aren’t going to mess anything up. There is documentation in the manual, I believe the remote control devices manual, something like that.
If you’ve got an MCU Pro there are no drivers to install. If it’s an older MCU you will need to install the drivers. Once installed, go to the “Devices” menu, click the “+” sign, choose Mackie Control, set the midi input and output ports and you’re ready to go.
I’m using 2 firestudio projects. So…when I set up the midi i/o’s what do I select?
My options in the input dropdown are,ALL MIDI INPUTS, Project MIDI,USB Audio Device (4 of them).
The Output dropdown options are…Project Midi, USB Audio Device (4 of those also) and Microsoft GS wavetable
