It’s been many years. I’ve tried everything… sorry haven’t documented every step of the way. Windows 7 and 10, endless operating system tweaks, including related to cpu parking. I think making the qu work as an audio interface in general is a waste of time (and believe me I’ve wasted the time to prove it).
I still love my Qu-SB. It’s the center of my band’s live rig. The ipad app is awesome, reliable, and the dynamics on each channel, along with eq, is very easy to use in realtime (live adjustments) and makes all the difference. But I had to give up on using it to stream VST instrument output over usb due to unrelenting glitches.
I bought a steinberg UR44C, and it is delivering glitch free VST streaming at incredibly low latency with no issues. So now I have the Qu as the audio mixer (don’t use it for audio interface/usb at all) and the UR for audio computer interface, and I’m totally happy. I also use the Qu for recording. The usb thumb drive recording is awesome (although you have to jump through some hoops to make sure the thumb drive is suitable and is formatted correctly).
hope that helps… wish i would have known that the audio interface aspect was useless a couple years before I gave up on it.
