I've recently purchased a Quantum interface. I've update Firmware to 1.1.0 and my Universal Control is version 188.8.131.52119. I am also running Studio One v184.108.40.206560. The Quantum is connected to my Windows 10 Desktop using a StarTech Thunderbolt adapter as recommended by presonus.
The Quantum connects fine and works well, both in Windows and S1. However, when opening Studio One, the sample rate is always automatically changed to 44.1 and is then grayed out in bot Universal Control and Studio One options.
If I close Studio One, I can set it to whatever I like and Windows reflects the change in its "Playback Settings", but as soon as Studio One launches and goes through it's startup scripts, it changes back to 44.1 and grays out all options to change it. - although, I can still change the block size and Clock Source.
Incidentally, if I run Reaper, it runs at 92k ASIO no problem...
