Well, maybe it has nothing to do with the problem, but there you go: the ESI is not a USB 2.0 class compliant audio interface, it's a USB 1.0 class compliant audio interface. Your Sound Devices MixPre-10T is USB 2.0 class compliant audio interface, and it works as an output for Vuo. This is what I would investigate further.
Maybe it's related, maybe it's not, but software I use for audio that rotates the audio scene often allow two possible sequences: Yaw -> Pitch -> Roll or Roll -> Pitch -> Yaw.
Is it something that would be pertinent to include in the node?
