Hi,
Yes, you are right, I’m on Mac.
What is definitely not correct, to use the very same MIDI Port as Mackie HUI and as Quick Controls Input. Unfortunately, I don’t really know, how are the MIDI Ports named on Windows. But if MIDI IN 2 is in use for Mackie HUI, use the Arturia KeyLab Essential MIDI In for the Quick Controls, please.
If this settings wouldn’t work (but my guess, this settings is correct), just try to switch the MIDI Ports:
- MIDI IN 2 for for Quick Controls.
- Arturia KeyLab Essential MIDI In for Mackie HUI
From the MIDI Port Setup > In ‘All MID In’ column, disable the MIDI port, which is in use for Mackie then, please.
