Gain-Q Interaction while using MIDI Controller
I'm afraid Gain-Q interaction currently only works when adjusting the parameters with your mouse. It does not work when manually entering values, or when using an external controller. Basically we've simply reverse linked the mouse behavior for these two buttons when Gain-Q interaction is enabled.
At the moment I don't have a workaround available, but we got a few requests on this and are investigating internally.

I'm currently using much of Pro-Q 4 with my Akai MidiMix controller, and I love the workflow. But one thing I noticed is that Gain-Q Interaction doesn't follow when I'm adjusting gain of a band on my controller. It only works when using my mouse. Is there any way I'm able to have it work with my MidiMix?
