Furthermore, the high end devices we are talking about are currently
the only means to get out low-jitter, multichannel, digital audio

try to broad their market by such a simple thing as implementing OS
X master volume control.
The RME devices do allow their internal hardware mixer's software
interface (TotalMix) to be controlled by standard MIDI CCs or
standard Mackie Control MIDI protocol. The MIDI ports used can be
CoreMIDI virtual ports that your app creates and uses to send/receive
the appropriate messages.
It's a great shame that manufacturers don't appear to be interested
in implementing the CoreAudio playthrough protocols that would allow
host apps to implement direct control of hardware multichannel
routing/volume, ie the equivalent of "ASIO direct monitoring". Then
again, pretty much no major host apps implement it either (?), so
manufacturers don't see it as being worth any effort. Chicken & egg.
