Hello LunaTech,
I am glad you still use the preset for zed.
After first look at QU-24 documentation, I see the following. It is more targeted to be remotely controlled then control DAW, but it can. They provide complete MIDI specification, which is nice. I do not see they transfer everything they can, for example they do not transfer "Fader touched" and fader resolution is just MIDI.
I do not understand your question about HUI. The device itself is not HUI capable and Sonar is not able to understand HUI. They have software translator on Mac for other DAWs, but such translator on Windows is not going to help with Sonar integration.
I am a bit busy these days, but something basic like ZED preset (with adopted number of controls and Fader/LED feedback) can be done quickly. In any case there are going to be some try/error/fix cycles, I mean I doubt it will work instantly since I do not have anything comparable for checks. Do you have time and possibility to test the preset and describe problems?
